以某高层建筑逆作法项目为研究背景，采用ABAQUS有限元软件对逆作过程进行施工过程的数值模拟分析。对支护结构与主体地下结构相结合的深基坑建立了考虑土、支护结构、水平支撑体系和竖向支承系统共同作用的二维平面有限元模型，采用弹塑性的修正剑桥本构模型模拟基坑开挖过程中土体的非线性特性，分析了地下连续墙水平位移与墙身弯矩随施工过程的变化以及地下连续墙与立柱桩的沉降及其差异沉降。

Based on the top-down project of a high-rise building, this paper carried out the analysis of numerical simulation of the top-down process of the construction process by applying the finite element software of ABAQUS. A two-dimensional finite element model considering the interactions between the soil and structures is set up to simulate the construction procedures of a deep foundation excavation supported by permanent structure. The elastic-plastic modified Cam-clay constitutive model is used to present the behavior of the soil. At the same time, this thesis also analyzes the horizontal displacement and moment of the diaphragm wall with the change of construction process as well as the settlement and differential settlement between erect column and diaphragm wall.
