摘　　要：基于ABAQUS有限元分析软件,结合天津文化中心交通枢纽Z1段实际工程,建立了超深地下连续墙工字钢三维有限元模型,研究天津软土地区水文地质条件下的超深地下连续墙体工字钢接头处的水平位移变化趋势及其接头处的薄弱渗流面,可在工程施工准备和施工过程中,进行数值模拟预判,为工程设计、施工过程中可能出现的问题与风险提前给出了较全面的分析,并可为超深地下连续墙施工组织设计的编制提供可靠地依据,确保施工质量和安全。A model of 3D-H-steel ex-deep in diaphragm wall is set up with an actual project of Zl-section of Tianjin euhural centre transport hub. The horizontal displacement trends of H-steel joints and its weak seepage sur- face are studied under the hydro geological conditions of Tianjin soft-soil area. ABAQUS can be used to predict the construction preparation and construction process. The predicted results can be used to analyze potential problems and risks of engineering design and construction process. Meanwhile, it can provide reliable foundation for the preparation of the ex-deep diaphragm wall construction design and ensure the quality and safety of construction.
