某水电站重建放空洞布置设计
Layout Design of Reconstruction of Empty Discharge Tunnel of a Hydropower Project
摘要
Abstract
A hydropower project adopted the layout of fully combined discharge cavity and diversion tunnel,as well as the layout type of pressurized and non-pressurized tunnel.After the impoundment of the hydropower station,the right bank slope was creeping and deformed,and after 3 years of operation,it encountered a 7.0-magnitude earthquake.After the earthquake,it was found that the shaft of the gate of the emptying tunnel was deformed and staggered,and the jam of the flat plate accident gate could not be lifted.In this paper,through the research and analysis of the causes of gate shaft failure,combined with the topographic and geo-logical conditions of the hub area and the layout of the hub,the layout scheme of the reconstruction emptying tunnel is proposed.关键词
