摘　　要：本文针对凤亭河水库坝坡存在的稳定性安全隐患,将数值分析法和刚体极限平衡法相结合,确定坝体可能的滑裂面位置,并对加固后的坝坡进行稳定性计算,结果表明,坝坡抗滑稳定安全系数符合规范要求。该方法可有效减小最危险滑裂面的搜索工作量,提高计算效率,可为类似工程提供借鉴。The analysis method of combining numerical analysis and rigid limit equilibrium method is adopted to determine possible critical slip surface location of the dam aiming at stability safety hidden danger of Fengting River Reservoir dam slope. The stability of the reinforced dam slope is calculated,and the results are consistent with requirements in the specification. The analysis results show that the stability analysis method of the dam slope can reduce the search workload of the most dangerous slip surface effectively,and the calculation efficiency can be improved,thereby providing reference for similar projects.
