The Simulation of Foundation Pit Construction on Basis of Strength Reduction Method and the Research on its Stability
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.
