摘　　要：桃源水电站在设计之初对泄洪闸检修采用“围堰挡水检修泄洪闸设计方案”,即上游设置浮式检修闸门,下游未设置检修闸门而采用围堰。电站投产后,下游围堰方案已不满足电站实际运行需求。文章针对桃源水电站下游增设检修设施进行研究,初步设计了在设计条件下自身稳定的无闸墩支承的浮式检修闸门的方案。At the beginning of the design of Taoyuan Hydropower Station,the “design scheme of cofferdam for maintaining discharge sluice” was adopted for the maintenance of discharge sluice,which is,floating maintenance gate is set in the upstream and cofferdam is used instead of maintenance gate in the downstream.After the station was put into operation,the cofferdam scheme in the downstream could not meet the actual operation requirements of the station.Based on the research on adding maintenance facilities in the lower reaches of Taoyuan Hydropower Station,this paper preliminarily designs a stable floating maintenance gate without pier support under the design conditions.
