摘　　要：以上海化学工业区围海造田工程为背景,首先计算了海堤在高潮位和潮位降落过程中堤身的渗流场,在此基础上结合堤前滩地各种不同冲刷程度,对海堤稳定性进行数值计算分析,得到了该海堤工程在潮位降落过程中堤前滩地冲刷程度与海堤稳定性之间的变化规律,得出了滩地合理保护宽度应该为9 m的结论。Under the background of land reclamation project in Shanghai chemical industry district,the seepage fields of seawalls at tidal level dropping are calculated here.According to the different degrees of erosion of the beach,the numerical calculation and analysis are made about the stability of seawalls.Through the numerical calculation,the relationship and rule of the landslide stability and erosion degrees of the beach at high tide level and tidal level dropping in this land reclamation project are obtained, at the same time,a conclusion is achieved that the suitable width of beach protection should be 9 m.
