摘要
结合日本阿武隈川地基渗漏防治工程中所遇到的问题，应用有限元饱和－非饱和渗流解析，对地基渗透破坏发生机制及其影响因素作了分析和讨论。经过对地基防渗处理方案的解析，明确了各种方法的优劣和适用条件，指出了地基防渗处理中应当注意的问题。
With the problems encountered in protecting the seepage failure of ABUKUMA river in Japan, we discussed the mechanism and the influencing factors of seepage failure in the foundation of river embankments using the saturated unsaturated flow FEM analyses. In this paper, we discussed superiority and inferiority of the protecting methods as well as the applicable conditions for them. Furthermore, also discussed some key points in the protecting project.
