Abstract

The design and practice of a deep excavation in shanghai was presented. The FEM based on Mohr coulomb Model was adopted to analyze the deformation of the excavation and its effect on adjacent buildings. This method gives good prediction of both the deformation of the soil retaining structures and the settlement of the soils behind the wall after comparing with measured datas. Meanwhile, the method is suitable to deformation analysis of sensitive environment circumstance.
