Factors Influencing Deformation of Excavation Pits and Numerical Simulation with Finite Element Method

Factors influencing deformation of excavation pits are one of important contents of its deformation control,which are developed to simualte and analyze in detail with the system of the optimized design with deformation control and the numerical simulation with finite element method in deep excavation-pit engineering (SDCDEFEM).Measured and simulated data of maximum settlement,maximum displacement,maximum swell and their places are statistically analysed.The statistic formula estimating maximum deformations and their places of deep excavation pits are obtained.Economical and effective measures of deformation control are put forward.
