简介：试用被坝所围住的水从2008年9月27日在三座峡水库被继续。在Hefeng有强壮的变丑和失败()山崩当水库水水平从173m的高度下降了时。它显示变丑是仔细与水库水变化有关。为这个原因，在变丑的水库水的效果被学习，拿象在这篇文章的一个例子的Hefeng山崩。首先，强壮的变丑区域的地质的特征和变丑状况被分析透露内在的因素和在水的条件下面的变丑的模式铺平变化。第二，山崩的稳定性在升起并且下降的过程，和在水库水水平变化和山崩变丑之间的相应关系期间被计算进一步被识别。最后，渗出物领域和在井的线下面的山崩身体的力量条件被分析揭示水库水的效果。而且，为更好可渗透的水库山崩，在水库水升起期间，渗出物力量的有利效果削弱相反的效果，这能被结束高举强迫水库水升起稳定性上的小效果，和没有变丑被引起了；但是在下降水库期间流水，渗出物力量的相反的效果在uplift力量的相反的效果上被附加，它引起稳定性戏剧性地减少并且在山崩前面导致累积身体的失败。
