摘　　要：以毛坦水库除险加固工程为研究对象,介绍了毛坦水库存在的病险问题及除险加固方案,采用拱梁分载法进行了毛坦水库除险加固后坝体结构安全的计算分析,并用有限元法进行验证,两种计算结果均表明坝体结构安全问题已解决,同时分析了挑流消能及坝面防渗等问题,验证了毛坦水库除险加固措施有效,可为类似工程提供参考。Taking the reinforcement of Maotan reservoir as study object,this paper introduces the existing safety hazards of the reservoir and the corresponding reinforcement scheme.The trial load method is used to conduct the structural safety calculation and analysis of the dam after reinforcement,and finite element analysis is employed for verification.The results of both methods indicate that the safety issues of the dam structure have been resolved.The paper also analyzes issues such as energy dissipation during discharge and seepage control on the dam surface.It is confirmed that the reinforcement measures for Maotan reservoir is effective,providing valuable reference for similar projects.
