| 摘 要： | 立波作用下的底沙运动关系到港口的规划和建筑物的安全。本文以实验为基础，综合前人研究成果，得到立波作用下床面形态及冲刷类型。对较粗颗粒底沙在立波作用上进行受力分析，得到了一周期内沙粒累计推移距离，净输沙率及冲刷强度。认为冲刷形态的不同与近底速度和加速度的分布密切相连。

| Abstract: | The sediment movement on the bed plays an important role on the planning of ports and waterways and the stability of structures. This paper is based on experiments. The erosion forms and parterns are proposed from experiments and other people' s researches. In this paper. stress on bed load are analyzed by standing waves. The accumulated moving distance, the net sand transport rate and the scouring instensity in a period of bed load are also given. The erosion forms and patterns are related with water particles velocity and acceleration near bottom. |
