摘　　要：笔者以柳州市独山水库连拱坝为研究对象,针对坝高不足、坝基及坝体渗漏等问题,结合现场实际,提出采用坝顶加高改建、坝基坝肩帷幕灌浆、连拱墩座坝体充填灌浆、连拱坝体防渗及防碳化处理等加固措施,并通过有限元法对大坝加固前后的坝体进行应力分析复核,为大坝除险加固措施方案和安全稳定运行提供有效的理论支撑依据。该研究成果可为类似中小型连拱坝除险加固提供参考。The authors take the multiple arch dam of Dushan Reservoir in Liuzhou City as the research object,aiming at the problems of insufficient dam height,dam foundation and dam body leakage,combined with the actual situation,the reinforcement measures such as dam top heightening and reconstruction,dam foundation abutment curtain grouting,multi-arch pier dam body filling grouting,multiple arch dam body seepage prevention and anti-carbonization treatment are proposed.The stress analysis and review of the dam body before and after the dam reinforcement are carried out by the finite element method,which provides an effective theoretical support for the dam reinforcement measures and safe and stable operation.The research results can provide reference for the reinforcement of similar small and medium-sized multiple arch dam.
