摘要
高坝消力塘作为防护下游河床的结构,其自身在高速水流冲击下的安全性是实现消能和防冲目的的关键所在,国内外都不乏破坏的实例。近年来,我国拟建和在建的一批具有世界级水平的300 m量级高坝,消能问题十分突出。消力塘防护结构的稳定性是当前水工水力学学科的前沿课题之一,也是实际工程所面临的亟待解决的课题。结合多个工程水垫塘模型试验研究,对不同底板防护结构稳定问题进行系统的阐述。
The safety of protecting structure in high dam plunge pool is the key to success or failure of energy dissipation.In recent years,a batch of high dams is under construction in China.The problem of energy dissipation is critical,and it is also the problem that needs to be solved in practice.In this dissertation,based on a few model tests,stability of different protecting structure in plunge pool are proposed by the synchronous measure of hydraulic parameters.
