摘　　要：汇源水电站由大坝、发电引水闸等建筑物组成,大坝为浆砌石拱坝。针对大坝存在的抗洪能力低、坝体最大拉应力不满足规范要求、坝体轻微渗漏及绕坝渗漏等问题,提出了扩孔、加高两种可选方案,进而对两种方案进行比选分析,从坝体稳定性、施工等多方面综合考虑,选择了扩孔方案作为解决该水库防洪能力弱问题的最优方案。对选定方案的坝体进行应力分析复核,分析结果满足规范要求。除险加固后能够消除大坝的安全隐患,为解决同类问题提供了设计思路。Huiyuan Hydropower Station consists of dams and diversion sluice for power generation.The dams is a masonry arch.In terms of the problems as low flood resistance,the maximum tensile stress of the dam unable to meet the requirements,the seepage of the dam or around the dam,two alternative solutions are put forward,namely reaming scheme and heightening scheme.Considering the stability and construction of the dam,the reaming scheme is chosen as the best plan to improve flood control capacity after comparing and analyzing.The stress analysis of the reinforced dam body is reviewed,and the analysis results meet the requirements.The hidden dangers of the dam can be eliminated by the treatment,offering a reference for similar engineering.
