Analysis and Research the Influence about the Control from the Excavation Way to Deformation of Foundation Pit

Different excavation methods present different influence on the deformation of foundation pit.Combining with engineering example,it analyzes and researches the excavation way of the reserved soil after foundation pit excavation.And through the application of the finite element software MIDAS GTS,it carries on the numerical simulation for the impact of section excavation sequence and different section length on the deformation.Ultimately it determines the optimal excavation sequence and length,and achieves the purpose of control deformation during construction.
