摘　　要：以乌江银盘水电站为例,介绍了该电站发电厂房坝段须提前挡水的原因及所采取的工程措施;对厂房挡水时的整体稳定性和建基面的应力进行了复核;采用三维有限元法,对厂房结构挡水时的受力状态进行了分析;根据计算工况,提出了计算方案,对计算结果进行了分析。经数值计算验证,提前挡水的方案合理、可行。In the construction of Yinpan Hydropower Station , the powerhouse section of the dam is required to retain the water ahead of schedule .Reasons of this requirement and corresponding engineering measures are introduced .Then, the overall stability of the powerhouse and the stresses along the foundation plane are evaluated .Also, the stress state of the powerhouse structure under the water retaining condition is analyzed with the three dimensional finite element method . The results show that the ahead-of-schedule water retaining scheme is feasible .
