摘要
基坑工程随着城市建设向着超深超宽的方向发展,本文基于Plaxis 2D采用硬化弹塑性土体(HS)模型对徐家棚超深基坑进行了数值模拟。研究了周围环境和基坑开挖的相互影响,得到了支护结构的位移、内力以及地表沉降,对采用逆作法的超深基坑的围护结构设计提供了一定的工程经验。
The development direction of the excavation is towards the ultra - deep and ultra - wide with the city construction. Base on the Plaxis 2D, the Hardening soil model was used in the simulation of Xu jiapeng ultra - deep foundation pit. The interaction of the surroundings and foundation pit was studied. The displacement and inernal forces of the support structure and the settlement of the surroundings were got. The eoclusion can provide some engineering references for the ultrap - deep foundation pit used reverse constrution.
