摘要
以北京地铁5号线雍和宫站开挖支护工程为背景,用有限元软件ANSYS建立分析模型,对车站浅埋暗挖施工的不同开挖顺序下,周边土体的位移、应力等相关内容进行了分析,指出围岩的应力和位移的状态,对推动地下工程施工力学的发展具有重要意义。
A finite element analysis of the tunnel at shallow depth method in lama temple of Beijing metro was conducted with the help of ANSYS. The distribution of displacement and stresses of the different excavation-support methods of the tunneling at shallow depth method for the covering soil during excavation are studied, points out the state of rocking stress and movement, has a very important meaning in promoting the development of underground projects mechanics of construction.
