Construction technique for comprehensively harnessing of landslide in Shuibuya Hydro Porject

Based on the special environmental and geological characteristics at the dam site of the Shuibuya Hydro Project and the reality of project construction,an introduction was given to the construction schemes for comprehensively harnessing of the five landslides below the Shuibuya Dam,including anti-slide pile construction,anchor cable construction,slope cutting and load reduction,open-cut overlying stratum,and drainage construction,with emphasis placed on the former two techniques.The analysis of safety monitoring data shows that the landslides after harnessing are in stability,verifying the effectiveness of the construction technology adopted in the project.
