摘　　要：本文基于Plaxis有限元方法,选取不同的地层损失率,对盾构隧道过程中引起的防汛墙沉降进行数值模拟。因本工程尚未实施,为确保盾构掘进时对防汛墙影响在可控范围内,本文根据有限元计算结果提出了一些措施以确保施工顺利进行。施工完成后可以将监测数据与有限元软件计算结果进行对比分析,验证有限元计算的准确性,为将来类似工程的有限元计算提供依据。In order to research the ground settlement of flood wall induced by shield tunneling, the ground settlement was modeling by PLAXIS finite element method with different solid loss rates. Since the project has not yet been implemented, the control measures of the settlement are proposed to reduce the settlement, which could provide some references for the smooth implementation of tunnel projects. After the completion of the construction, the monitoring data can be compared with the finite element software calculation results to verify the correctness of the finite element calculation, and to provide the basis for the finite element calculation of similar projects in the future.
