摘要
本文采用Duncan－Chang模型和新型接触面单元编制了二维有限元程序DSAF，用于圆形地下连续墙开挖过程的分析模拟，算例分析结果与工程实测值较为接近。
This paper introduces 2D finite element program DSAF prepared by using Duncan-Chang rnodel and a new contact surface unit. This new program can analyze and simulate the process of the excavation of the circular di-aphragm wall. The analyzed results obtained by the calculations fairly approach the measured values achieved from engineering practice.
