国内某大型水电站右岸砂石加工系统后边坡冲沟曾经发生过泥石流自然灾害,后因地制宜对边坡多条泥石流沟进行防治,并经过几年施工期的运行证明,采取“清理、拦护、引排”等措施,实现“水石分离”,对防治泥石流自然灾害的发生,作用较为明显。本文总结了该水电站右岸砂石系统后边坡泥石流沟治理措施,并对其治理效果的经济性进行分析。
After a natural disaster of landslide occurred in the slope gully of the right slope bank gorges of a large-scale hydropower station in China, a number of debris flow ditches in the slope were controlled according to local conditions. After several years of operation, it was proved that “clean-up, Row ”and other measures to achieve“ separation of water and stone ”, the prevention and control of debris flow natural disasters, the role is more obvious. This article summarizes the management measures of debris flow ditch behind slope on the right bank of the hydropower station, and analyzes the economy of its control effect.
