摘要
基于北京地下直径线工程DK6＋804．1～DK7＋060段的施工设计，介绍了CRD工法施工工序，并采用有限元程序软件对CRD工法施工的各步进行模拟计算，并对计算结果进行分析。
The construction procedure of CRD excavation method is introduced based on construction design of DK6 ＋ 804.1 - DK7 ＋ 060 section of Beijing Rail Underground Transit Line Project. Each step of CRD method is numerically simulated by using finite element program and the results are analyzed.
