【摘要】：中梁一级水电站位于重庆市境内的大宁河干流上,在其水库初期蓄水运行时,大坝下游的坝脚被冲毁,库区近坝右岸发现有硝洞槽-郑家大沟变形体,因而水库处于限制水位运行状态。针对上述情况,工程建设单位和运行管理单位进行了认真的分析研究,根据分析结果,制定出了适宜的修改方案和措施,并严格执行蓄水方案,对水毁部位进行了修复;工程验收小组接受委托对水电站水库进行了蓄水验收复核,同时,对变形体进行了专题研究。目前已完成了对水库的竣工验收工作,工程运行正常、安全。修复后的良好运行状态表明,研制出的方案和措施可为水利水电工程的蓄水验收工作提供借鉴。
[Abstract]:Zhongliang Grade I Hydropower Station is located on the Danning River main stream in Chongqing City. During the initial storage operation of the dam, the dam foot downstream of the dam was washed out, and the nitrate hole trough-Zhengjiagou deformed body was found near the right bank of the dam in the reservoir area. Therefore, the reservoir is in the state of limited water level operation. In view of the above situation, the project construction unit and the operation management unit have carried on the serious analysis and research, according to the analysis result, has worked out the suitable modification plan and the measure. And strictly implement the water storage program to repair the damaged site; The project acceptance group has been commissioned to review the water storage acceptance of the hydropower station reservoir, and at the same time, has carried out a special study on the deformable body. At present, the completion and acceptance of the reservoir has been completed, and the project is running normally. Safety. The good operation condition after restoration shows that the developed scheme and measures can be used for reference for water storage and acceptance of water conservancy and hydropower projects.
