汉江陈家咀滑坡基本特征与稳定性分析
摘要:陈家咀滑坡为某水电站的近坝滑坡，滑坡若失稳将对位于上游的大坝水工建筑物和电站发电产生影响，是该电站首要解决的重大技术课题。通过工程地质测绘、钻探、平硐、岩土测试等大量勘察工作，查明该滑坡体积约240万m3，为大型岩质切层滑坡，现状整体上处于基本稳定状态，建坝前后叠加暴雨久雨滑体饱水等多种工况下，滑坡整体上多处于欠稳定一不稳定状态，为此滑坡需要采取工程治理措施。经比较，建议结合大坝三期围堰建设对滑体采取削坡减载（用作围堰填筑土料）+前缘抛石护岸的工程措施，使滑坡稳定达到安全标准。
Abstract:Chenjiazui landslide is Hanjiang Gushan hydropower station near the dam landslide, landslide if instability will affect the dam of hydraulic structures located upstream and power generation, is a great technical subject first to solve engineering Gushan hydropower station. Through the engineering geological mapping, drilling, adit, rock and soil testing a large number of survey work, find out the landslide volume of about 2 400 000 of m3, is a large rock cutting landslide, the overall situation in the basic stability of the state, before and after completion of the superposition rainstorm long rain sliding body of water saturated conditions of the landslide, on the whole is unstable to an unstable state, so need to take measures for landslide. By comparison, the proposed combination of dam three stage cofferdam construction to take the slope to reduce load on the landslide (used as cofferdam filling material)+front riprap revetment engineering measures, the landslide stability meet safety standards.
