摘　　要：坝基中存在松散覆盖是产生渗漏的首要条件 ,渗漏量过大 ,直接影响工程效益 ,且因渗漏力的长期作用下 ,将产生颗粒位移管涌破坏。为此防渗处理方案选择是十分必要的。通过对横泉水库坝基渗漏稳定分析 ,进行了合理防渗处理方案比较 。Loose overburden existed in dam foundation is the primary condition for the china appearence of seepage.If the seepage condition is worse,it will directly influence the project benefit.And also,with the long-term effect of seepageforce,piping damage such as grain displacement will happen.Therefore,the selection of seepage trestment scheme is quite necessary.Through the seepage stability analysis of Hengquan reservoir dam foundation,this paper makes a reasonable comparison of seepage treatment schemes,which is beneficial to the contruction of project and development.
