摘 要:
本文使用锦屏一级、溪洛渡、糯扎渡三个大型工程的水垫塘1∶100水弹性块体模拟底板的水工模型研究了块体失稳条件。并采用专门设计的测试块体承受脉动上举力装置,测试了块体具有一定抗力条件的受力过程。进行了回归分析,给出了一定抗力条件下的安全水深,或一定水深条件下所需抗力(板重力和加锚固)大小的公式。本文对护底或护坡不护底的水垫塘塘底破坏性分析都有参考意义。[著者文摘]

Abstract:
The destabilization conditions of apron slabs in plunge pool are studied by making use of hydraulic models with a scale of 1 : 100 of hydropower stations Jinping I , Xiluodu and Nuozhadu. The loads on slabs with certain resisting force are measured by a special instrument. The regression analysis is carried out. The formula for the safety depth of water-cushion under certain resisting force or the resisting force needed under certain depth of water-cushion is given. This research has significant reference for failure analysis on plunge pool with apron slabs in the bottom or that with apron slabs on the slope.[著者文摘]
Key words:
hydraulic structure; plunge pool; stabilization of slab; with apron slabs on the slope; safety depth of water-cushion
