The Numerical Analysis of Stability against Upheaval of Foundation Pit

Abstract:

Great region discrepancy exists in natural soil, while analysis and calculation of stability against upheaval of foundation pit in current specifications is only to soft soil. In order to study the stability against upheaval of foundation pit bottom in different geological conditions, FLAC3D numerical analyzing software is adopted to calculate and visualize the influence that several factors cause to stability safety coefficient, and contrast and checking is also made with current analysis and calculation methods and normal formula of stability against upheaval of excavation. The study shows that : a increase in soil’s cohesion,internal frication angle and embedded depth can develop the stability against upheaval of foundation pit.
