摘要
本文对沙质海岸直立堤前的冲刷形态及冲刷机理进行了研究,指出立波作用下堤前冲刷有三种形态,即相对细沙型、相对粗沙型和粗沙型。并从紊流边界层及传质速度出发,探讨了三种冲刷形态的冲刷机理。最后提出了三种冲刷形态的判别标准。
The scouring patterns and mechanisms in front of vertical breakwaters on sand coastal are approached in this paper.There are three scouring patterns of sand bed in the front of a vertical breakwater under the action,of standing waves: the relatively fine sand type,the relatively coarse sand type and the coarse sand type.The scouring mechanism of each pattern is probed in the light of turbulent boundary layer and velocity of mass transport.The judging mode of the three patterns is presented.
