Abstract: Based on the theoretical analysis results, the bearing behavior of squeezed and branch pile under vertical load and lateral load was analyzed in this paper. The mean works include the influence of vertical load on the pile lateral bearing capacity and influence of the lateral load on the vertical load bearing capacity. The factors influence the bearing capacity of pile such as elastic modulus of soil around and under pile bottom, pile length, plate position are also analyzed.

Abstract: During the Qin and Han Dynasties, there were several types of bridges, such as wooden poles and wooden beam bridges, arch bridges, gallery bridges, Zhandao, floating bridges and so on. These bridge remains are mainly located in Guanzhong area, Sichuan province and other areas. All these are important data for us to understand bridge shapes, construction technology, means of transportation, and social life of the Qin and Han Dynasties.

Abstract: A series of asphalt mortars were prepared and tested by dynamic shear rheometer and other common evaluation methods aiming at investigating the physical performance of asphalt mortars. The final analysis shows that the changes of strength modulus and viscoelastic property rely on the composition differences in asphalt mortar, and modified asphalt and neat asphalt mortar have apparent different stress responses, and in micromechanics aspect, the asphalt mortar system with higher filler content is easy to be destroyed at high temperature and high shear frequency.

Abstract: Soil samples are taken from two experimental roads in Heilongjiang province for the test. Then a prediction of shear strength is carried out, basing on a three-layer BP (back propagation) network in Matlab, the hidden layer, output layer and training function of which adopt non-linear transfer function tansig, linear transfer function purelin, and trainbfg function respectively. It is found workable to predict factors influencing shearing strength using BP neural network with given soil properties. Prediction results of cohesion strength for clay show a better performance than those for sandy soil, while results of friction angle for sandy soil are better than those for clay. It is indicated that BP neural network does a better work in predicting the friction angle than that of cohesion.

Abstract: Along with the global energy shrinking, building energy conservation and emissions reduction has become a major topic in the field of industrial engineering. The advanced technology of OPC UA (Object linking and embedding for Process Control Unified Architecture) has been introduced in order to solve the problems of interoperability and intercommunication between each subsystem and the underlying devices. On this basis, the OPC UA client and server has been developed, the public building energy efficiency control simulation system has been built and the target of real-time monitoring and controlling energy efficiency information has been achieved.

Abstract: A common phenomenon in modern architecture is the over emphasis on technology at the expense of natural environment, regional culture, and human emotions. In this essay, the regionalism spirit in architectural design is introduced for future reference in architectural design.

Abstract: For concrete structure durability increasingly highlight of problem, focus description has chlorine ion on concrete structure of erosion mechanism, and invaded model and effects factors, derivation out integrated consider concrete of chlorine ion combines capacity, and chlorine ion proliferation coefficient of time dependence, and concrete structure micro-defects effects and the mixed coagulation s performance of practical proliferation equation, established has for forecast concrete using life of chlorine ion proliferation theory model, made intends built structure in chlorine ion environment Xia durability design thought and design method, Perfected design theory of durability of concrete and carbonation model design based on Carbonation depth of concrete during the period, compared with the concrete cover thickness, for engineering design and revision of the specification reference.

Abstract: With the development of our country economy, more and more super tall buildings are being built. While its beauties attract the attention of the people and they provide sufficient and comfort space to our people, it is very important to evaluate and its safety during severe earthquake. In this paper , the research method is studied for the tall structures during severer earthquake based on the design experience and research of tall structures. Based on the mechanical and deformation characteristic of this tall structure, the bottom stories and stories above the strengthened ones are selected as the "key stories" to control the performance of the building. The structure is replaced by an equivalent single degree of freedom system corresponding to each mode and each equivalent displacement is determined using the proposed method.

Abstract: The development of green building is the only way to protect the environment and resource conservation, construction parts green degree evaluation is an important measure to promote green building. In this paper, based on the classification of construction parts, to build a green degree evaluation index system, through the application of information diffusion, computer simulation, curve-fitting techniques, establishing a major construction parts green degree evaluation function. Based on this function so you can develop evaluation systems and databases for the construction parts, providing a scientific and concise way for the evaluation of green degree, effectively promoted the development of green buildings.

Abstract: Twice serious deformation occurred in the Wangxia unstable rock mass in 2010 and 2011 in Wushan country in the Three Gorges Reservoir. It formed a large dangerous factor for the local resident and channel safety. Based on the detailed investigation of the new cracks, deformation history, GPS observations, total station monitoring and crack displacement monitoring data analysis, analyzed comprehensively the deformation and reasons of the unstable rock. The researches show that the deformation type of the unstable rock mass contains gradual change and mutation, should adopt the corresponding monitoring methods and monitoring frequency in different deformation stages based on the geological survey and monitoring the key parts of the unstable rock mass. The destruction of the Wangxia unstable rock was a gradual process, controlled by 5 key cracks, which were crack T11, T12, T13, T16, and T10, consider the Wangxia unstable rock was subsided extrusion type collapse.
