Simulation of Deep Excavation and Shoring with FEM Based on ADINA
Based on the deep foundation pit project of Wanbang Square in Qingdao, after many times numerical simulation of foundation pit with ADINA, the relationship conclusions were summed up by changing parameters of anchor rope and excavation step: The horizontal displacements of shoring structure became smaller by making the length of anchor rope longer or making the number of anchor ropes more or making the excavation step more; the uplift of the bottom of the foundation became smaller and the sedimentation of the surface became smaller by making the excavation steps more. It can offer reference to optimization of foundation pit supporting structural scheme.
