摘　　要：凤凰水库由于建设时间早,运行年限长,大坝坝体填土结构较松散,渗透性中等,坝体填筑质量不满足现行要求,亟须进行工程加固达标建设。针对大坝渗漏存在的主要问题进行分析研究,采取针对性防渗加固处理方案,实现了大坝坝体防渗达标稳定运行,为类似大坝防渗加固建设提供技术参考。Fenghuang Reservoir,due to its early construction period and long operating history,has a relatively loose filling soil structure in the dam body,with moderate permeability.The quality of the dam body’s filling quality can not meet the current requirements.It is urgent to carry out the construction of engineering reinforcement up to standard.The main problems of dam leakage are analyzed and studied,and the targeted anti-seepage reinforcement treatment scheme is adopted to realize the stable operation of the dam body,which provides technical reference for the construction of similar dam anti-seepage reinforcement.
