摘　　要：以钢板桩+锚杆作为护岸结构的苏南运河常州西段"四改三"航道升级改造工程为实例,通过反演分析得到合理的土体计算参数,同时在反演分析的基础上,引入动态反演分析的方法,结合工程实际,对施工过程中的三个主要阶段逐次进行分析,并与现场实际监测位移值进行对比分析,为每一个阶段的变形提供可靠保证。对比结果表明模拟值与实测值吻合较好,表明反演结果是可信的,可为类似的工程提供参考。Based on the Su＇ nan canal ＂four to three＂ channel upgrading project in Changzhou, and it revetment structure composed of vertical steel sheet pile and anchor, the reasonable calculation pa- rameters of soil has been obtained through inversion analysis. Based on the result of the inverse analysis, dynamic construction factors was considered. Also, three work progresses have been analyzed successively combined under practical engineering condition. Monitoring displacement of the plies was compared with the analyzed result to make sure the safety of each work progress. The results show that the simulation results are in good agreement with the measured values, which indicates that the inversion results are credible and can provide reference for similar projects.
