摘要
波浪在库岸边坡破碎时,由水体紊动、破波压力和波能产生的上举力使库岸泥沙颗粒处于悬浮起动状态,并在沿岸坡向的破波回流作用下被带走,最终造成库岸边坡的冲刷变形.在实测各向破波压力和岸坡变形的基础上,得到了波浪作用下岸坡泥沙起动公式,并对其进行了修正.
When waves break in the reservoir bank, the up -ward force produced by the turbulent flow, the broken wave pressure and the wave energy causes the bank sediment pellet to remain in a suspending state. The sediment pellet would be carried off by the broken wave backflow along the bank, which causes scour distortion. On the basis of broken wave pressure and bank distortion, the bank sediment threshold motion formula with wave action is deduced.
