摘要
文中主要研究不同开挖方式对基坑工程围护结构变形的影响。依托实际工程,采用MIDAS GTS NX有限元软件对工程阶梯型开挖、水平分层分块开挖和水平分层开挖进行数值模拟。探究在模拟中,不考虑时间因子的条件下,开挖选型对围护结构变形的影响。研究表明围护墙变形从小到大依次为工程分层开挖、阶梯型开挖,分层分块开挖。
This paper studies the influence of different excavation methods on the deformation of foundation pit re⁃taining structure.Based on the actual project,MIDAS GTS NX finite element software is used to carry out numerical simulation of stepped excavation,horizontal stratified excavation,and horizontal stratified excavation.The influence of excavation type selection on the deformation of retaining structure is investigated without considering the time fac⁃tor.The results show that the deformation of the retaining wall from small to large is stratified excavation,stepped ex⁃cavation,and stratified excavation.
