以广州地铁二号线为工程背景,使用有限元程序 Plaxis 对几种不同工况下盾构施工对桩基的影响进行了分析,通过用简化的解析计算法的结果进行对比验证了数值模拟的正确性,对以后类似问题的解决有一定借鉴作用。
Taking the project of Guangzhou Metro Line 2 as an example, the influence of shield construction on pile foundation under several different conditions is analyzed by the finite element program Plaxis. The numerical simulation is verified by comparing with the simplified analytical method. Correctness has some reference to the solution of similar problems in the future.
