摘　　要：苏州河河口水闸(以下简称苏闸)运行至今出现了诸多病险问题,已严重影响安全运行。因苏闸工程的特殊性,难以使用常规的风险识别方法。为了保障水闸的安全运行,基于故障树风险分析方法,按照功能边界将苏闸划分为5个子系统;确定了各子系统存在的26项故障模式,建立了苏闸故障树(Fault Tree Analysis),通过下行法确定一阶、二阶、三阶、五阶最小割集,识别苏闸的风险源为“地基不均匀沉降”“底轴不均匀变形”以及“监测系统缺陷”。研究成果不仅为管理部门提供了水闸风险管理的建议,而且对同类工程的设计、维护、监测、管理具有重要的参考价值。So far,many dangerous problems have appeared in the operation of Suzhou River Estuary sluice,which has seriously affected the safe operation.Because of the particularity of Suzhou River Estuary sluice project,it is difficult to use conventional risk identification methods.In order to ensure the safe operation of the sluice,based on the fault tree risk analysis method,the Suzhou River Estuary sluice is divided into five subsystems according to the functional boundary;the 26 fault modes of each subsystem are determined,and the fault tree analysis of Suzhou River Estuary sluice is established.The first-order,second-order,third-order and fifth order minimum cut sets are determined by descending method.The risk sources of Suzhou River Estuary sluice are identified as“uneven settlement of foundation”“uneven deformation of bottom axis”and“defects of monitoring system”.The research result not only provides suggestions for the sluice management department,but also has important reference value for the design,maintenance,monitoring and management of similar projects.
