基于增量法的深基坑阳角变形数值模拟
Numerical simulation analysis of deep foundation pit positive corner deformation based on incremental method
摘要
Abstract
Finite difference numerical simulation on the negative comer is,based on incremental calculation method,by means of FLAC3D,conducted in order to study the negative corner deformation law of deep foundation pit.Results show that the method of end well excavation after standard segment excavation is more conducive to the stability of negative corner and the maximum displacement of negative corner is 45％ less than the original construction plan under the identical condition of supporting structure and way and that displacement of positive comer presents attenuation trend with the decrease of cross sectional area of steel support and that the reasonable reference range of cross sectional area-0.06 ～ 0.09 m2-of steel support in similar engineering is given.The research can provide reference for similar foundation pit engineering,which makes the construction of irregular foundation pit more reasonable,reliable,safer and economical.关键词
