摘要
本文以浙江省某地区高层建筑深基坑施工为研究背景,根据基坑的支护方案、监测数据等资料以及用Midas GTS有限元分析软件对该基坑开挖阶段的分析所得数据为依据,分析软土地区深基坑开挖阶段支护桩的变形特性。结果表明基坑开挖阶段的水平最大位移发生在最后一次开挖阶段,且最大位移在桩体的腹部;随着基坑的开挖,支护桩的变形由前倾型逐渐变为凸肚型,水平位移也随之变大。
Taking the deep foundation pit construction of a high-rise building in a certain area of Zhejiang Province as the research background,based on the data of the supporting plans and monitoring data of the foundation pit and the analysis data obtained by Midas GTS finite element analysis software,the analysis of the deep excavation stage support Pile deformation characteristics.The results show that the maximum horizontal displacement in the excavation stage of the foundation pit occurred in the last excavation stage,and the maximum displacement was in the belly of the pile;with the excavation of the foundation pit,the deformation of the retaining pile gradually changed from a forward-inclined type to a convex one.Type,horizontal displacement will also become larger.
