【摘要】 本文通过上海地铁二号线一期工程延伸段江苏路车站采用多道支撑地下连续培作为基坑开挖的支护结构的设计实例，介绍地下连续墙入土深度的计算确定，并通过模拟地下连续墙深基坑的分步开挖过程建立连续计算模型，采用有限元分析了墙内弯矩、墙体侧移、支撑轴力随开挖过程的变化。更多还原

【Abstract】 Based on the design for the multiple diaphragms to support the foundation pitexcavahon inShanghai No. 2 Metro Line, Ihe calcualtion and determination of the depth of thediaphragm in the soil is described, and by mimicking the process of stepped excavation, a model is established in the computer, through which analysis is given of the internal torque, lateral movement and supporting axial force of the diaphragm wall using the finite element method.更多还原
