摘要
黄河上游茨哈峡—拉加峡段水力资源丰富,布置有三座大型水电站,该河段滑坡发育,对水电工程构成不利影响。本文从区域条件、坝址区岩体结构面特征、典型滑坡危害等方面,分析滑坡形成机制及与水电工程的相互影响。黄河深切峡谷形成的高陡岸坡是滑坡形成的首要条件,岩体内不利结构面是滑坡形成的控制性因素,区内55处滑坡中有15处对水电站工程区构成危害,危害形式主要有滑坡失稳及滑坡涌浪,部分滑坡危害巨大,上述分析可为后期水电工程开发中滑坡防治提供基础资料。
From Ciha gorge to Lajia gorge,there are rich hydraulic resources and three large hydropower stations in Upper Yellow River. This area develops a lot of landslides,which can adversely affect hydropower project water-power engineering. This paper will analyze the mechanism of landslide formation and interaction with water-power engineering by regional conditions,dam site rock mass structural plane characteristics,typical of landslide hazards.Primary condition caused landslide is high steep slope cut by yellow river. Rock adverse structural plane is the controlling factor of landslide. There are 15 landslides constitute a risk to water-power engineering. The landslideinduced disasters take in both the landslide and the landslide surge.,some bring great damages,This analysis provides the base values for landslide control in the development of hydropower projects.
