摘　　要：湘潭电厂灰坝至今已运行10余年,地质勘测查明排水系统和棱体均已失效,而且当年采用山坡土风化料筑坝,均匀性和质量较差,因此渗漏现象严重。针对渗漏最严重的1号坝,采用二维有限元,进行了计算分析。通过对渗流场及其渗透变形、边坡稳定等的综合分析,对1号坝进行了安全评价,提出了可供设计参考的加固处理建议。The ashery dam NO. 1 of Xiangtan Power Plant has been put in service more than 10 years, the drainage system and filter toe of the dam have lost their efficacy. Owing to the dam is built of weathered rock-soil materials and is unevenly compacted, so the dam leakage is very serious. Based on the analysis on the seepage field, seepage deformation and slope stability of the dam with 2-D FEM computation, the assessment on dam safety and the suggestion on dam reinforcement are given.
