摘　　要：李家峡水电站地质条件复杂，边坡稳定问题突出，边坡稳定核算及治理设计一直是本工程重要技术问题之一。坝址区开挖边坡中，以双曲拱坝在拱端下游坝肩边坡的稳定尤为突出，是边坡稳定核算和治理的重点区域。在该区域边坡治理实施过程中通过观测资料分析和复核计算，不断地完善、及时修正设计和施工方案，有效地控制了施工期的边坡稳定。Because of complex geological conditions of Lijiaxia hydropower station, slope stability is a striking problem.Check computation of slope stability and treatment design is one of key problems of the project. Among excavation slopes of dam site, the stability of the downstream slope on the left dam abutment is the important area of check computation of slope stability and treatment. In slope treatment of this area, design and construction plan were revised and improved by means of analyzing observation data and recheck computation. This efficiently controlled the slope stability during construction.
