摘　　要：水闸工程已运行多年,为全面分析工程结构的安全状态需进行结构安全复核,文章主要对涵洞结构进行安全复核。复核结果表明,涵洞结构边墙、底板承载力满足规范要求,顶板承载力不满足规范要求,且涵洞顶板中部存在顺水流向裂缝。为确保工程安全运行,须尽快按照处理措施对其进行除险加固。The sluice project has been in operation for many years,therefore structural safety check is required to analyze the overall safety state of the engineering structure.This paper mainly focuses on the safety-evaluation of the culvert structure.The results show that the bearing capacity of the culvert bottom plate and side wall meet the requirements of the code,but the bearing capacity of the culvert roof fails to meet the requirements of the code,for the cracks in the direction of seepage flow.To ensure the safety of the project operation,the culvert structure should be reinforced as soon as possible according to the treatment measures.
