摘　　要：以旺盛江水库第三溢洪道加固工程为例,介绍了溢洪道公路桥及启闭机房工作桥的优化加固方案内容。依据公路桥梁及启闭机房工作桥梁的技术状况评定材料提出了拆除的加固方案,但工程实际情况表明,原加固方案已影响到整个工程的安全度汛。为了缩短第三溢洪道加固工程的施工工期,确保旺盛江水库安全度汛,提出了保留公路桥梁及启闭机房工作桥梁的优化加固方案,并依据其混凝土材质分析和结构承载力验算结果两方面内容,验证了优化加固方案的可行性。分析与验算结果表明,公路桥梁及启闭机房工作桥梁具有足够的安全余量,保留二者能够最大程度的满足施工需求,且具有节约经济成本的优势。Taking the No.3 Spillway Reinforcement Project of Wangshengjiang Reservoir as example,an introduction was made on the optimization contents of reinforcement scheme for the spillway road bridge and hoist room working bridge.The bridges had been proposed to be dismantled according to the technical status assessment file.However,the actual situation of the project shows the original reinforcement scheme is not able to guarantee the safety of the project in flood season.In order to shorten the construction period of No.3 Spillway Reinforcement Project and en⁃sure the safety of Wangshengjiang Reservoir through flood season,the optimized reinforcement scheme retaining the bridges was proposed.The feasibility of the optimized reinforcement scheme was also verified by the results of con⁃crete material analysis and structural bearing capacity calculation.The results of analysis and calculation demon⁃strate the road bridge and hoist room working bridge have sufficient safety margin and retaining them is able to meet the construction requirements to the maximum extent at less cost.
