摘　　要：龙滩水电站1号机引水洞进口边坡存在多处由断层、夹层、节理或层面等地质结构面切割而成的块体群,对建筑物安全构成隐患。规模最大的块体约8.5万m^3,通过对该块体进行稳定分析,提出适当的加固处理措施。经过4年多的监测,1号机块体加固方案达到预期效果。其成功治理可为其他规模庞大的边坡块体加固工程提供参考。The first diversion tunnel intake slope of Longtan Hydropower Station has many unstable blocks which are formed by fault,interbedded layer,joint and bedding surface.The biggest block is about 85 000 m3.The slope stability was analyzed and these blocks were reinforced by deep anchorage,surface supporting and seepage control and drainage.After four years operation and monitor,the slope is stable.
