Analysis And Simulation Of Stability And Deformation Of Deep Foundation Pit Engineering

Due to the rapid growth of the rapid development of city construction and the emerging of city population, the development of the surface area is less and less, so the use of underground space and facilities has become an inevitable trend. With the emergence of a large number of deep foundation pit, and the scale and depth of excavation are constantly increasing. The foundation pit engineering involves and stability problems of soil mechanics strength, deformation, but also relates to the common effect of soil and supporting structure and hydrogeological and engineering geological problems. Also with the computer technology, testing technology, construction equipment and technology are closely related. Is a kind of theory can be integrated technical disciplines development. The focuses on deep foundation pit supporting earth pressure calculation method, the stability of foundation pit contents and evaluation and deep foundation pit deformation analysis theory, and established the foundation pit excavation model combined with finite element analysis software, thus for deep foundation pit excavation the whole stability and deformation for several numerical simulation analysis. The main issues of this paper are as follows:(1) The existing calculation theory of deep foundation pit overall stability and the bottom of foundation pit seepage stability further, in detail the classic calculation method at the same time, according to the simulation theory and Simulation on the part of the calculation method for the optimization and correction.(2) The mechanism of deformation of foundation pit deformation, including the wall around the heave and pit ground movement, detailed analysis. Related content and monitoring method of foundation pit deformation monitoring. In addition, the prediction method of foundation pit deformation is described and compared.(3) Utilizing ANASYS finite element analysis model is established, on the stability of foundation pit were ahead of the numerical calculation and analysis, of earthwork of foundation pit excavation and support process of stage should stress and displacement prediction for foundation pit construction to provide strong theoretical data.(4) Compared with the similar research results, the general rules of stability and deformation analysis of foundation pit are obtained.
