Experimental Research on Fluctuating Pressure Characteristics of “Revetment-Protected and Non-Bottom-Protected Plunge Pool” of High Arch Dam

Abstract

In the construction progress of hydropower project, the energy dissipation security was always the focus of design and research. When the river overburden and water cushion was deep enough, the deep water cushion can be used for the energy dissipation design, and a new type - “Revetment-Protected and Non-Bottom-Protected Plunge Pool” was studied and proposed, whose stabilization was directly effected by the fluctuating pressure on the plate surface and back. The experimental research of fluctuating pressure was carried out on the 1:50 hydraulic model, and characteristic of fluctuating pressure was studied and summarized in this paper.
