水闸安全等级评价中防洪标准的研究分析

Research and Analysis of Flood Control Standards in Evaluation of Sluice Safety Level

案例水闸位于中山市三角镇,该区域大部分水闸建于二十世纪五六十年代,经过多年运行,水闸出现了运行安全问题。本次通过对案例水闸闸顶高程、堤顶高程以及水闸过流能力进行复核计算,研究分析水闸防洪标准评价等级,查找水闸安全隐患。计算结果表明,水闸防洪标准评价为C级,后期可有针对性地进行除险加固或者重建,确保工程运行安全。

Case sluice is located in Sanjiao Town of Zhongshan City,most of the sluices in this area were built in the 1950s and 1960s,and after years of operation,the sluices have encountered operational safety problems.This paper has reviewed and calculated the sluice top elevation,embankment top elevation and the overflow capacity of the sluice,studied and analyzed the evaluation level of the flood control standard of the sluice,and found the potential safety hazards of the sluice.The calculation results show that the flood control standard of the sluice is evaluated as grade C,and the risk-eliminating reinforcement or reconstruction can be carried out in the later stage to ensure the safe operations of the project.
