坝基土渗透稳定分析与对策研究

Seepage Stability Analysis of Dam Foundation and Study of Countermeasures

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.
