摘要：

在近岸区,泥沙有沿岸输送和向岸一离岸输送。对于某一局部地区而言,则输入的泥沙量大于输出的泥沙量,则出现淤积,否则出现冲刷。天然岸滩在动力条件的长期作用下,处于动力平衡状态,即已调节到泥沙的输入量和输出量相等。故其岸滩剖面能保持稳定。当建造海岸建筑物后,原来的动力条件受到破坏,因而在建筑物的周围出现冲刷或淤积。本文讨论在以向岸—离岸输沙为主的情况下,由于海岸建筑物的建成而出现的建筑物前的局部冲刷,着重讨论了以下三个问题:(1)建筑物前的水深与冲刷过程的关系。(2)建筑物前海床的最大冲刷深度。(3)建筑物前海床的冲刷形态。文中广泛地介绍了近期的国际研究成果,也扼要说明了本文笔者的一些见解。
