长期降雨、大雨和暴雨对各类边坡稳定性的影响是十分明显的。据统计在雨中和雨后发生滑坡的达80％以上。但直到目前为止,国内外尚无专门的研究和讨论。笔者认为尽管造成滑坡的原因很多,看法也并不完全一致,处理和解决这类问题的理论和方法也不完全相同。然而,从宏观上看,降雨对滑坡的影响是十分重要的。为了有利于露天矿边坡的设计、研究 Long-term rainfall, heavy rain and heavy rain on the stability of various types of slopes is very obvious. According to statistics, more than 80% of landslides occur in the rain and after rain. But so far, there is no special research and discussion at home and abroad. The author believes that although there are many reasons for the landslide, the views are not exactly the same, and the theories and methods for handling and solving such problems are not exactly the same. However, from a macro point of view, the impact of rainfall on the landslide is very important. In order to favor the design and research of open pit slope
