摘要： 下株梧水库位于山东省安丘市西南部，总库容1 620万m3，最大坝高20.87 m。该水库运行已近50 a，大坝曾多次发生险情。大坝渗流有限元计算以及渗透变形分析结果表明，大坝坝脚存在渗透变形的可能性。

Abstract: The reservoir storage capacity of Xiazhuwu reservoir located in southwest of Anqiu city is 16.20 million m3 with 20.87 m dam height. The reservoir has been in operation for 50 years with several dangers. The results of dam seepage element calculation and seepage deformation analysis proved the possibility of existence of seepage deformation in the dam foot.
