摘　　要：作为密云水库调节池的重要构筑物,小西库挡水闸的稳定性对水库库容及安全运行有很大影响。水闸右侧闸墩外观检查后发现有一贯通裂缝。采用刚体极限平衡法对其进行安全复核分析。结果表明:水闸右边墩正截面受弯承载力略小于作用值,不满足规范要求,对结构安全极为不利,须进行进一步处置。As an important structure of the regulating pool of Miyun Reservoir,the stability of Xiaoxiku Retaining Sluice has a great influence on the reservoir capacity and safe operation.A crack was found after the appearance inspection of the pier on the right side of the gate.The rigid-body limit equilibrium method was used to check the safety of the system.The results show that the flexural capacity of the normal section of the pier on the right side of the sluice is slightly less than the function value,which does not meet the requirements of the code,and is extremely detrimental to the safety of the structure.
