摘　　要：文中以某港实际工程为依托,结合软黏土不排水强度弱化模型,采用有限差分软件FLAC3D建立沉箱式防波堤动力分析模型,探究在波浪荷载作用下,软土地基弱化效应对沉箱式防波堤稳定性的影响,获得防波堤在竖向和水平复合加载下结构承载力破坏包络线用于判别结构整体稳定性.Based on the actual project of a port,combined with the undrained strength weakening model of soft clay,the dynamic analysis model of caisson breakwater was established by using finite difference software FLAC3D.The influence of weakening effect of soft soil foundation on the stability of caisson breakwater under wave load was explored,and the failure envelope of structural bearing capacity of breakwater under vertical and horizontal combined loads was obtained to judge the overall stability of the structure.
