Numerical Simulation Analysis Of A Deep Foundation Pit Support

This paper's operation process is according to the technical route on the basis of deep foundation pit supporting research literature,on the basis of the summarized of the structure of supporting schemes and the scope of application,with Baotai building project of deep foundation pit as an example.This paper takes someone building foundation in shenzhen as an example,the foundation pit is divided into seven different profile according to the site engineering geological conditions.This paper design how to support the 7-7 profile with the Lizhang 7.0 software,and get the changes of shear stress about the Supporting pile,get the horizontal displacement curve of foundation pit,get the settlement curve of the solid around of the foundation pit and the regular of the soil pressure distribution.According to the design of supporting schemes to construct,according to the Monitoring specification to set up monitoring stations.Then establishes numerical model with FLAC3 D on the basics of someone foundation pit in shenzhen,simulate the process of the supporting foundation pit,get the change of horizontal displacement,get the settlement curve of the solid around of the foundation pit,get the changes of shear stress about the Supporting pile and the horizontal displacement curve.Finally Compare the design value,the monitoring value and the simulation value,analysis of the supporting pile shearing force,the horizontal displacement and the the change of the foundation pit horizontal displacement and settlement.The result of comparing showes that the curves of the three basic is almost the same,that proves the practicability of numerical simulation and the rationality of the design.
