针对红江水库大坝安全鉴定报告书及水利部水工程安全与病害防治工程技术研究中心的水库核查意见,指出红江水库主坝存在的安全问题,对主坝不同部位提出除险加固措施。通过多种方案的比较,最终选择培厚上游坡+垂直防渗方案,保证了主坝设计的安全和经济合理性。水库经过1年多时间的运行,外坝坡明显干燥,坝脚观测渗流量明显减少,主坝存在的问题得以解决。
According to the reservoir safety assessment report of Hongjiang reservoir dam and the water resources engineering safety and disease prevention engineering technology research center of reservoir verification opinion, pointing out the main dam of Hongjiang reservoir safety problems, different parts of the main dam proposed measures of reinforcement. Through the comparison of various schemes, the plan of thickening the upper slope and vertical seepage control plan is finally selected, which ensures the safety and economic rationality of the main dam design. After more than one year’s operation, the dam has been obviously dry and the observed seepage volume at the foot of the dam has obviously decreased. The problems existing in the main dam can be solved.
