摘　　要：月牙河水库修建完成后发挥了巨大的效益,随着宁阳县的不断发展,原设计库容已无法满足现状用水需求,水库进行增容工程设计是十分必要的。通过方案比选,确定采用疏挖方案以改善现状水库库容,采用Geo-Studio软件分析增容对水库渗透稳定的影响,结合大坝情况选取两个剖面进行计算。结果表明,采用疏挖方案增容,原特征水位参数保持不变,大坝整体安全性仍在允许范围,但大坝渗漏量有所增大,应提高防渗加固措施。After the completion of the construction of Yueyahe reservoir,great benefits have been brought into play.With the continuous development of Ningyang county,the original design capacity of the reservoir has been unable to meet the current water demand,so it is very necessary to design the reservoir capacity increase project.Through scheme comparison and selection,the dredging scheme is adopted to improve the reservoir capacity.The Geo-Studio software is used to analyze the seepage of the reservoir after the capacity increase.Two sections are selected for calculation according to the dam conditions.The results show that the original characteristic water level parameters remain unchanged,the overall safety of the dam is still within the allowable range,but the dam leakage is increased,which should be improved anti seepage and reinforcement measures.
