摘要

利用波浪水槽试验,对风浪作用下库岸的表面波压力和介质孔隙水压力响应进行了研究。试验中观测了在不同波高、周期、水深、坡比和介质等条件下的库岸动力响应。试验结果分析表明:糙率和渗透系数对表面波压力影响较大,介质孔隙水压力与波陡、沿程相对位置、渗透系数密切相关,孔隙水压力响应随着深度增加存在幅值衰减和相位滞后现象。

Abstract

A flume test is used to analyze the surface wave force and porewater pressure on the bank slope of a reservoir under different conditions. On the basis of the experiment result, it shows that roughness coefficient and permeability coefficient are the more important factors influencing the wave force of bank surface, and that the wave steepness, relative position along the depth and permeability coefficient are close relative with the porewater pressure. Simultaneously, the pore water pressure will be attenuated in amplitude and lagged in phase with increase of water depth.
