Architectural form factor is the reflection of architectural surface and decide its forms. This paper use extenics design analysis and make analysis on architectural design examples from four basic elements including point, line, surface, body. It is aimed at making better and clear relationship of abstract elements and finding the content in architectural design forms.

Abstract: As the depth and the length of the various underground cavern is increasing, the stability analysis of surrounding rock is very important. This paper first gives the analytical solution equation of the circular tunnel. About the city-gate water tunnel with no analytical solution, it can be solved by numerical method, which is based on the large finite element software ANSYS. The form of a calculation model for conveyance city-gate water tunnel was established. With the D - P criterion, it is nonlinear calculated for the computation of water conveyance tunnel. Then it is obtained that the stress characteristic and development of plastic zone characteristics of the surrounding rock of city-gate tunnel. It also gives the relationship between the development of plastic zone, plastic strain and coefficient of horizontal pressure, the internal friction angle. The last, it is analyzed the relationship between the different parameters and the plastic zone development of different parts of tunnel cavern. This result can provide technical reference for design and the tunnel construction.

Abstract: During operation, due to change of outside temperature, edge of abutment and central part of concrete arch dam is prone to stress concentration, Concrete of tensile stress concentration area appears too large tensile stress easily, which results cracks to affect dam safety. This paper, by changing the material properties, that obtained high strength low elastic modulus of concrete, replaced arch rings with gradient material replacement method, to improve the stress state of dam and enhance strength for dam safety. By comparing the temperature rise with drop of the arch stress distribution area, the relationship of changing elastic modulus and stress has got. Using the VT technology acquire critical values of mutation elastic modulus.

Abstract: In geotechnical engineering, the support pattern regularly applied is continuous wall, whose high security, strong adaptability, good stability and other characteristics have been widely appraised in engineering circles. This paper use Midas to build the three-dimensional research model on varied construction stages of foundation pit, in which the foundation pit applies the scheme of combing continous wall and inner support. Further more, this paper makes estimation on the machenical stability in varied construction stages of foundation pit and use strength deduction method to analyze the stress and strain conditions of foundation pit in different working states, the results acquired from which researches have certain reference to the engineers.

Abstract: Aimed at the student the result problem, give student the result data scoops out the model. The decision tree method is a very valid classification method, in the data that scoop out. According to student the result data characteristics, adopted the C4.5 decision tree algorithm. C4.5 algorithm is the improvement algorithm of the decision trees core algorithm ID3, it construct in brief, the speed compare quickly, easy realization. Selection decision belongs to sex, scoop out the result enunciation, that algorithm can be right to get student the result data classification, and some worthy conclusion, provide the decision the analysis.

Abstract: This paper sees the underground construction shield tunnel and foundation trench as study object. It has analyzed disturbance mechanism and ground deformation mechanism, which were caused by shield tunnel and building pit construction. Through the system analysis of ground deformation influence factor, it has confirmed main influence factors, like geological environment condition of overall consideration, physical parameter and construction technology. And it has established ground deformation prediction model based on neural network. Then it has made sensitivity analysis of affecting ground deformation factor by neural network hierarchical analytical approach.

Abstract: After a literature survey, the application of 3D seepage-consolidation coupling FEM model based on Biot theory and Cam-Clay model for simulating deep excavation dewatering in soft soil is studied. A foundation pit in East-China is taken as an example and 3D finite element method is used to simulate the dewatering and excavation. Through the 3D finite element analysis, the three-dimension numerical method can be applied to study the deformation behavior of foundation pit and surrounding soil. The numerical simulation experience and data presented in the paper can be refereed in the design, construction and research of similar projects.

Abstract: The Full decoration residential comply with the developed economic and improved residents' living standards. On the basis comparing the decorate between China and western countries, The full decoration residential should take systematic design and pay attention to the decorate strategy.

Abstract: With the digital development of city construction, the construction of three-dimensional Geographic Information System plays an important role for the urban construction planning and decision-making. 3D urban planning geographic information management systems need to be able to put different spatial data, information of urban construction, urban planning information into the same platform. The integration of information resources whick provids a variety of spatial information based on the intelligent application services is the core. This article puts urban planning geographic information management related to business needs in-depth analysis, and put forward a three-dimensional geographic information model which is used for integrated management of data and can be dynamically adjusted for urban planning and management of business processes.

Abstract: The design and construction of the viaduct route of the urban metro have a big influence on the urban spatial layout. As a kind of landscape structures with both dynamic and static properties, it brings not only convenient transportation but also the whole cityscapes change. This article aims to solve the effect on the urban spatial environment and the crowd around through the research on the design method of metro viaduct bridge modeling, researching the layout design of surrounding landscape along the viaduct, rebuilding the cityscape and cultural axis and exploring the method of solving the contradiction and conflicts in the process of city and metro construction.
