堤前立波运动及其引起的海床冲刷

STANDING WAVES AND SCOURES OF A SAND BED IN FRONT OF A VERTICAL BREAKWATER

用ＭＡＣ法（ｍａｒｋｅｒａｎｄｃｅｌｌｍｅｔｈｏｄ）对直立堤前任意物面边界的立波运动进行数值分析，并得到实验资料的验证，对立波作用下直立堤（暗基床式、突基床式）前海床冲刷的冲刷形态、冲刷机理、冲刷坑的预报等问题进行了较系统的分析研究．

he standing waves with arbitrary boundary conditions are calculated byMarker and Cell Method. The scouring patterns, scouring mechanism and the prediction ofscouring trough of sand bed in front of a vertical breakwater under standing waves are systematically investigated, based on experiments and numerical analysis.
