但人们也知道，2002年到2003年一年间，北京的地下水水位下降了三米。

It was shown that the great variation of effective unit weight and angle of internal friction of soil could result in the increase of seepage failure probability of earth dams, the effect of variation of angle of internal friction of soil was greater, and the seepage failure probability of earth dams was sensitive to variability of dam seepage. In addition, the increase of water level in reservoir would also induce great increase of seepage failure probability of earth dams.

结果分析表明，坝体渗透破坏的概率随着土体有效重度和内摩擦角变异性的增加而增加，并且土体内摩擦角的变异性对坝体渗透破坏的影响较大，坝体渗透变异性对坝体渗透破坏的影响较大；另外，随着库水位的升高，坝体发生渗透破坏的概率也显著增加。
