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.
