Building energy efficiency;Residential buildings;The evaluation system
摘要:
The consumption of building energy will be reduced in the future development, and the development of energy-efficient buildings will be a trend. The buildings have been divided into four classes, like the residential building, the public building, the industrial building and the agricultural building. As the energy evaluation of buildings had played an important role in the environmental construction, therefore the research was mainly focus on the residential building of energy evaluation work, by the analysis both on home and abroad about building energy evaluation of status, and combines national and area enacted of about building energy of evaluation standard, to construct a residential building evaluation system, and for the evaluation work service of residential building of energy by introducing a full of about the residential building evaluation system of constructed process.
摘要:
The calculations of plan truss and beam-girder method on straight bridge were analyzed, which determined right beam-girder method calculation model of the box-girder bridge. Based on this model, the different radius continuous curved box-girder bridges were simulated by finite element, and then the internal forces of the bridge were obtained. The calculations of inner beam and outer beam show the change rule of internal force and bridge radius. The reasonable calculation methods of continuous curved box girder bridges are obtained, which can offer help to the bridge designers.

摘要:
The under earth pressure field and water pressure field action, the lateral pressures are provided by multi-field coupling. Neglect of the groundwater seepage field is one of the main reasons why measured values of water-earth pressure on supporting structures are generally very different from those calculated values. Under the action of seepage, seepage force changes soil effective stress and affects soil shear strength. We set up legitimate equations through calculating the interaction of the hindering force and seepage force under a multi-field coupling.
摘要:
5 masonry columns were strengthened by Sprayed Glass Fiber Reinforced Polymer (SGFRP) in this paper, and a research of the seismic behavior of them tested by eccentric loading experiment was presented. The failure modes of the strengthened masonry columns were illustrated and strengthening effects of them were discussed. The results showed that the bearing capacity of the reinforced columns increased greatly, and the ductility of them also improved significantly. Comparing the strengthening effects of the columns when the thickness of SGFRP and the number of glass fiber are different, some reasonable reinforce suggestions are proposed.

摘要:
The objective of this research was to develop and demonstrate native grass sod for sediment control from disturbed lands associated with California highways. The research evaluated native grass species for inclusion in sod and evaluated the sod at a California highway field site. Seed mixes, including rhizomatous and bunchgrass species, were evaluated in a greenhouse setting for six California ecoregions. Growth and sod development potential of each seed mix for each ecoregion were evaluated. Seed mixes for three California ecoregions were further evaluated with a reinforcement material, and for establishment and weed suppression. Establishment and weed suppression of select ecoregion seed mixes and reinforcement materials were evaluated. Results indicated that multispecies sod has potential for use in revegetation of disturbed lands associated with highways.
摘要:
The conductive properties of donor doped BaTiO3 semiconductor ceramic was studied with a quantitative model in this paper. Considering the influence of acceptor grain boundary segregation, a differential equation of electron level was established. According to a four order Runge-Kutta formula, the energy level of the grain boundary barrier was obtained at different temperatures numerically. Further, the PTCR effect of BaTiO3 semiconductive ceramics was calculated.
摘要:
The cracking bending strength for steel-polypropylene hybrid fiber reinforced concrete (HFRC) had been studied based on experimental test. the inicial cracking strength achieve significant improvement compare to plain concrete, and the highest increase is 16.7%. There is a synergistic effect exist when steel fiber is 1.0% in volume or polypropylene fiber is 0.1% in volume, and the synergistic effect raise to vertex (1.043) when both of those two requirements are fulfilled.

摘要:
In order to improve the hardness and strength of the permeable concrete, rigid polymeric fibers are mixed to the concrete. Compressive strength tests, flexural strength tests, tensile splitting strength tests and permeable performance tests prove that the rigid polymeric fibers could increase the hardness and strength of the permeable concrete. The optimized mix proportion and forming process are recommended to support the application of the permeable concrete.

Energy saving;Ground source heat pump;Low-carbon;Shallow geothermal energy
摘要:
Ground source heat pump system (GSHPS) takes the advantage of shallow geothermal energy, and it can not only provides heat apply but also provide cold making power in a high efficiency and energy saving way. The GSHPS is a low carbon technology and has applied into use. But in China it is a new technology and lack of application. The paper describes the theory of GSHPS, the advantages of GSHPS, the using feasibility of GSHPS and its limitations. Compared with traditional systems, in consideration of system running conditions, energy consumption and the level of environment pollution, the GSHPS can be more efficient and less ecological disruption. And with the developing of the GSHPS technology, it can have a considerable prospect.
摘要:
This paper mainly focuses on how to improve exploitation rate of coal bed methane (CBM) was presented in the paper. To enhance efficiency of exploitation of coal bed methane, the carbon dioxide or nitrogen gases were injected in the coal bed in the experiments. The injection of nitrogen gases in the coal bed could help increase the methane permeability. As a result, it showed that the injection of nitrogen gases could increase the stability and productivity of CBM.
摘要:
Coal reservoir in Shanxi is influenced by sedimentary environment, diagenesis and structure. The reservoir is characterized by heterogeneity and nonlinearity distribution. An intelligence evaluation model, based on modified particle swarm optimization (MPSO) algorithm with Elman neural network (ENN), is constructed. The model is corresponding to reservoir physical property by the use of logging, core and test data, and it is employed to classify rock types of coal reservoir. The case results indicate that this model is feasible and effective in the rock classification, so it provides an effective method for identification of lithology and mineral rock classification.
摘要:
Engineering bidding transaction market exists extensively asymmetric information. According to the information economics point of view, information asymmetric extremely easily leads to the moral hazard and adverse selection, which will cause project value can't get a real reveal in engineering bidding. Therefore, the project bidding on the trade market for the asymmetric information research has strong theoretical value and practical significance. this paper tries to use the method of evidence theory to have a certain extent measure in engineering bidding market of asymmetric information, in order to enrich the content of the bidding market research field, and provide a decision-making reference for relevant departments.

High temperature performance;Optimum fiber content;SMA-13 mixture
摘要:
At present designers take little account of the different requirements of pavement performance when determining the adding ratio of lignin fibers in Chinese SMA mixture. Basing on the high temperature performance the article studied the optimum fiber content of SMA-13 mixture through comparative tests of performance. First aiming at SMA-13 mixture with different fiber contents, the mix proportions were designed and asphalt contents were verified. Then the effect of fiber content on high temperature performance was indicated through three kinds of interrelated performance tests. At last other pavement performances of SMA-13 mixture were verified. Based on the test results, an optimum fiber content of 0.33% is recommended for the lignin fibers used in this SMA-13 mixture, with which mixture poses the best high temperature performance.
