Seepage Stability Analysis of Dam Foundation and Study of Countermeasures

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.
