摘要：
针对岩石裂隙表面粗糙度对裂隙渗流性能影响的问题,采用数值模拟方法研究曲折度对粗糙单裂隙渗流影响的机理研究.结果表明:曲折度与流量修正系数和等效渗透系数修正系数呈正相关且相等,最大偏差为8％.对同裂隙开度不同粗糙元裂隙模型进行渗流模拟时,发现随着出入口压差的增大,立方定律的不适用性越来越明显,其中流体通过矩形粗糙元单裂隙沿程损失和局部损失最大,同时偏离立方定律也最为明显;将基于曲折度修正立方定律应用于预测矩形和三角形粗糙元粗糙单裂隙渗流,并与其他六种修正模型进行对比,发现基于曲折度修正立方定律在预测粗糙单裂隙时能获得更为准确的结果.

摘要：
Rock pore is the storage space and migration channel of geo-fluid resource like petroleum, coalbed methane and shale gas etc. In this paper, the rock core microscopic pore structure based on CT image is studied through image processing. Then the parameters are analyzed statistically by numerical modelling. The reconstructed software Mimics is used to reconstruct the core structural model. Finally, the relationship between the pore structure parameters and penetrability is studied by numerical simulation. The equivalent permeability of the reconstructed core is calculated by using FEM software Abaqus. The results shown that fluid percolation is directly related with porosity, pore shape, pore conectivity. The permeability of core can be obtained by substituting flow numerical simulation for seepage laboratory experiment.<br/> ©2019 IOP Publishing Ltd. All rights reserved.

摘要：
This study investigates the effect of adding a small concentration (0-0.5 wt. % addition by mass of cement) of graphite nanoplatelets (GNP) to cementitious materials. GNP-water-surfactant suspensions with various surfactant concentrations (0-20 mg/mL) and sonication times (0.5-6 h) are prepared and subjected to different protocols (long-term standing and centrifugation). Then, dispersion and stability are qualitatively observed through digital imaging and scanning electron microscopy after long-term standing and quantitatively evaluated by calculating the absorbance spectra ratio. Furthermore, the mechanical properties of GNP-reinforced cement (GNPRC) are investigated. The results show that 8 mg/mL and 4.5 h are the best choices for the surfactant concentration and sonication time, respectively. Also, obvious reinforcement for the mechanical properties of GNPRC is found;specifically, the 0.05 wt. % addition of GNP increases the compressive strength by 7.5 % and 16.7 % after 7 days and 28 days curing, respectively. Then, between the GNP dosages of 0 and 0.5 wt. %, the flexural strengths at 7 days and 28 days continuously increase, up to 55.6 % and 53.3 %, respectively.<br/> Copyright ©2019 by ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959.

摘要：
In view of considering reservoir segregation, it is preferred that the permeability coarsening method is of great importance. Based on the mesh coarsening technique, the conceptual model of low permeability reservoir segregation distribution is established, and different permeability coarsening methods are selected to simulate the daily production of oil field and other parameters and the error analysis. The most appropriate permeability equivalent method and the grid step size are selected at last. It is concluded that the harmonic-arithmetic mean method is the best method to simulate errors of the parameters, and it is also the best way to calculate the equivalent permeability in low permeability reservoir considering the reservoir segregation distribution. After the coarsening, the grid step on horizon is 20 m or so and on vertical is 4-6m.<br/> ©2019 IOP Publishing Ltd. All rights reserved.

摘要：
Projects involving the construction of rock salt underground gas storage have several disadvantages, for example, effective management is not employed to manage the production information and data in the process of the project, resulting in duplication of data storage, waste of storage space, lower efficiency of data calling, and negative effects on the efficiency of data update. Therefore, a database and its management systems for a rock salt gas storage was constructed based on an SQL Server database system, primarily including the management forms of the geological modeling, storage simulation, stability evaluation, economic evaluation, and covering the addition and delete checks of static and dynamic data. The security of the system was improved by setting the administrator permission. The establishment of the database management system was of tremendous importance and it provided a significant technical support for the development of the gas storage project.

摘要：
The aim of this work is to investigate the influence of rice husk (RH) on the properties of mortar. Two different RH were used as integral additives in the mortar samples: Direct natural RH addition to the mortar and the use of pretreated RH. The results of such modification are described, taking into consideration the interaction between the RH and mortar. In addition, the physical properties, visual observation and microstructure of mortar prepared with different amount of modified RH were experimentally studied. The test results indicated that modification of RH enhanced the interaction between the RH and mortar because of the impurities removal and rougher surface. Comparing with the natural RH, the modification of RH increases the density and the mechanical properties. The addition of RH can increase the pore number of the mortar mixture, resulting in decrease in the density and mechanical properties of mortar. Morphology characterization results showed that the modification of RH results in an improvement in the interaction between the RH and mortar and further increase in RH content increases the number of pores in the mortar structure. © 2018 by ASTM International.

摘要：
This research aims to comparatively evaluate the high temperature properties of modified high viscosity asphalt (SHVA) by temperature and frequency sweep testing as well as repeated creep and recovery testing. Wheel-tracking testing was also introduced to verify anti-rutting properties of asphalt mixtures. The results indicated that the phase angles (δ) of high viscosity asphalts decreased with increased temperature. The lowest decrease rate of the complex modulus (G∗) reflected that SHAV had the lowest temperature susceptibility. The δ of neat asphalts were nearly unchanged with increased frequency, while the δ of modified asphalts clearly increased. Both temperature and frequency sweep tests indicated that improvements in anti-rutting performance (i.e., smaller δ and bigger G∗) of high viscosity asphalt were noticeable. Burgers model and a piecewise linear regression method showed high accuracy in simulating asphalt's creep process. Changes in binder creep stiffness and accumulated strain (i.e. 2.8, 2.6, and 2.4% for SBS, TPS and SHAV, compared to 96.4 and 102.9% for two neat asphalts) demonstrated that the polymer used in these modified asphalts significantly enhanced their stiffness and elastic properties. From the analysis of creep compliance, SHVA had the maximum elastic and minimum viscous proportions in comparison with the other four asphalts. Test results of the mixtures showed that the asphalt mixture with SHVA possessed the best high-temperature stability (9265 cycles/mm). Good agreement was found between the high temperature properties of the asphalts and mixtures. © 2018 Elsevier Ltd

摘要：
The aim of this study was to ecologically analyze the flow field and fluid pressure on the interlayer in the construction of salt-cavern gas storage in terms of terrestrial ecology. With the help of CFD software Fluent, the cavity numerical models in different working environments had been built and the influence of water injection rate, height of the central tube and inter-medium tube, height and length of interlayer had been analyzed. The results show that the existence of interlayer breaks up the continuity of cavity boundary and causes many ecological eddies in the storage, and the changes of factors have a great impact on the strength and scope of eddy in the small space of environment. The fluid pressure on the upper surface of interlayer is significantly less than the fluid pressure on the lower surface in most cases while the pressure equal to each other when the inter-medium tube goes down, so that it can be slump the interlayer easily through reducing the height of the inter-medium tube. © Foundation Environmental Protection & Research-FEPR.

摘要：
Ordinary concrete was modified with additions of superabsorbent polymers (SAPs). Research was conducted to assess the weight loss ratio from cyclic freeze-thaw tests, the shrinkage ratio, and the sulfate attack resistance coefficient of compressive strength for the modified concrete. The results indicate that freeze-thaw resistance, shrinkage resistance, and sulfate attack resistance were greatly improved when compared to the control concrete. At the same time, the microstructure of concrete modified with SAPs was examined using scanning electron microscopy (SEM). The SEM results revealed a modification mechanism of the treated concrete.

摘要：
In this study, the interaction between the silica filler and polydimethylsiloxanes (PDMS) was investigated from the aspects of the bound rubber and morphological characterization. With special attention to the dynamic properties, the dynamic test was conducted by dynamic shear rheometer. The results show that the modified filler disperses uniformly within the PDMS matrix without aggregation and connects closely with the matrix compared to that of the unmodified fillers. Surface modification of the filler increases the bound-rubber content. The increase in silica loading leads to an increase in the silica-silica interaction and a decrease in filler-rubber interaction, which results in the aggregation of fillers and the increase of the bound-rubber content. It was apparent that storage modulus, loss modulus, and tanδof unvulcanized PDMS/filler compounds filled with treated silica filler were lower than that of the untreated silica system. Moreover, the tanδdecreases with increasing silica loading.<br/> Copyright ©2017 by ASTM International.

摘要：
A new method, Dynamic Leaching Test (DLT), was put forward to analyse the leaching behaviour and leaching mechanism of heavy metals in solidification body of municipal solid waste incineration (MSWI) fly Ash. In this study, two groups of solidification materials were used, one with ordinary Portland cement (C), and the other with slag-and-clinker (SC). In each solidification body, solidification material/ (solidification material + MSWI fly ash) weight ratio was 25% and water/solid weight ratio was 0.3. After a 60-day curing period, DLT was applied to analyse the leaching behaviours and leaching mechanisms of lead and chromium in solidification body with a mathematical model based on Fick's first law. The test results showed that most of lead and chromium were leached out during the initial stage (0∼7d), and their leachability decreased greatly later. In the cement-based solidification body, the leaching behaviour of chromium is approximately consistent with Fick's first law. The leaching of lead is a combination of diffusion and acid erosion mechanisms. In the slag and clinker-based solidification body, the leaching of lead is approximately consistent with Fick's First law. The leaching of chromium is more complicated than simple diffusion or acid erosion, which indicated the need for further research.

摘要：
In this study, a form-stable lauric acid/expanded perlite (LA/EP) composite was prepared by absorbing paraffin into porous networks of expanded perlite. The form-stable composite was characterized by using Differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscope (SEM) techniques, durability and leakage test. Leakage test results showed that optimum and maximum mass fraction of LA contained in the composite without leakage is 70 wt.%. The FT-IR results revealed that there were physical interactions between the expanded perlite and the lauric acid. In addition, SEM images showed that LA can be quite evenly dispersed in the porous skeleton of EP. The melting temperature and latent heat of the form-stable EP/PA composite containing 70 wt.% lauric acid were determined as 43.2 °C and 105.58 J/g, presenting its suitable phase transition temperature, sufficient latent heat, good thermal stability for application as composite phase change materials (PCMs). The durability test showed that the leakage problems of PCMs composite can be greatly prevented because of the interaction between the expanded perlite and the LA. All the results suggested that the form-stable EP/PA composite has great potential in building applications for thermal energy storage. © 2015 Published by Elsevier B.V.
