摘　　要：里运河东堤位于南水北调东线,东堤沿线穿堤涵闸数量多且年久老化,存在严重安全隐患。针对上述问题,为检验交叉建筑物的安全性并且确保里运河东堤运行管理安全和沿线公众生命财产安全,选取里运河东堤高邮段的车逻闸为典型交叉建筑物,根据水闸安全评价导则,在现状调查和安全监测的基础上,对车逻闸进行安全复核计算。计算内容包括防洪标准复核计算、渗流复核计算、稳定复核计算以及消能复核计算4个方面,并结合上述各项安全复核计算结果分别进行安全性分级,最终确定水闸安全类别。The East Levee of Li Canal is located in the Eastern Route of South-to-North Water Diversion Project.There are many culverts and sluices crossing the levee along East Levee,which are aging and have serious security risks.In view of the above problems,in order to test the safety of the crossing structures and ensure the safety of the operation and management of the East Levee and the safety of public life and property along the levee,the Cheluo sluice of Gaoyou Section was selected as a typical crossing structure.According to the Guidelines for sluice safety evaluation,the safety check calculation of the Cheluo sluice was carried out on the basis of the current situation investigation and safety monitoring.The calculation included four aspects:flood control standard check calculation,seepage check calculation,stability check calculation and energy dissipation check calculation.Combining with the above safety check calculation results,the safety classification was carried out,and finally the safety category of sluice was determined.
