摘要：
To clarify some of the inconsistencies in the research of equivalent diameter of PVDs, we constructed 3-D consolidation models of PVDs and sand drains using ABAQUS and compared models with and without sand drain resistance. When the sand drain resistance was included in the model, the equivalent diameters of the sand drains were 30, 65, 78, and 100 mm (for a 100-mm-wide, 4-mm-thick PVD) corresponding to PVD drainage depths (or soft soil layer thickness) of 2, 5, 8, and 10 m. Except for the depth of 2 m, the other results were higher than the values found in previous studies. The equivalent diameters increased with increasing consolidation depths. When the well resistance was ignored, the equivalent diameters were 20 mm for all the ground consolidation depths, which was less than the value in most previous research findings.

摘要：
<jats:title>Abstract</jats:title>
<jats:p>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.</jats:p>

摘要：
A study presented findings on the behavior of ordinary concrete against superabsorbent polymers (SAPs) SAPs-modified concrete. Specimens were evaluated for resistance to freeze-thaw, shrinkage, and sulfate attack. Scanning electron microscopy (SEM) was utilized to investigate the modification mechanism. The cement used to prepare concrete samples was No. 42.5 Portland cement. The fine aggregate was a medium-coarse sand with a fineness modulus of 2.7 and a density of 1.57 × 103 kg/m3, in accordance with the specifications of JGJ 52-199. Tap water was utilized for all concrete samples. A base water/cement ratio of 0.4 was used to prepare specimens that incorporated 0.0, 0.1, 0.3, 0.5, 0.7, and 0.9% of the SAPs as concrete additives.
摘要：
A study was conducted to verify the validity of silane as an additive by monitoring the corrosion behavior of silane-enhanced mortar. Silane coupling agents were used in varying proportions, and the effect of the coupling agent content on mortar properties was studied. The integral silane mortar additive was (γ-glycidoxypropyl) methyldimethoxysilane (KH560). River sand with a fineness modulus of 2.43 was used as the fine aggregate. A water/cement ratio of 0.4 was used for preparing mortar mixtures incorporating no silane (the reference sample), and 1, 3, and 5% silane. Distilled water was used to prepare the mortars.
摘要：
A microemulsion was successfully prepared via polycondensation of alkoxy silanes. Research into the control of the preparation and properties of the microemulsion was conducted. The structure and properties of the microemulsion were characterized by transmission electron microscopy (TEM) and photon correlation spectroscopy (PCS). The variation in the temperature, the methods, and the amount of catalyst and surfactant was studied in relation to the properties of the final microemulsion.
