基于有限元分析的超高层建筑沉降后浇带封闭时间确定

Super high-rise building the finite element analysis of post pouring settlement belt sealing time is determined based on the

采用ANSYS软件,分析沉降后浇带封闭前主楼和裙房的相应沉降差以及封闭沉降后浇带后沉降后浇带是否会开裂,以判断能否在施工阶段封闭沉降后浇带。研究结果表明:对于采用CFG桩地基的高层建筑不需要设置沉降后浇带。

by using the ANSYS software, the analysis of post pouring settlement belt before the closure of the main building and the podium of the corresponding differential settlement and settlement after closure of post pouring settlement belt of post pouring belt will crack, to determine whether in the construction phase enclosed subsidence of post pouring belt.The results of the study show that：for the use of CFG pile foundation of high-rise buildings do not need to set the post pouring settlement belt.
