摘要
在分析滑坡的地质资料和气象资料的基础上,讨论了降雨诱发滑坡的机制,并深入探讨了滑坡与降雨的关系,包括:滑坡与降雨的分布特点、滑坡与降雨频次之间的关系、滑坡与降雨在时间上的关系等。结果表明:滑坡发生的概率和滑坡数量不仅与降雨量的大小成正相关关系,而且与滑坡发生的当天降雨及前期降雨特征关系密切。
Based on the analysis of geological and meteorological data, the mechanism of landslide triggered by rainfall and the relation of landslide with rainfall are analyzed. Furthermore, the characteristics of landslide and rainfall distribution, relation of landslide with rainfall frequency and the temporal relation of landslide with rainfall are discussed. Finally, it gets some conclusions that the occurrence probability and the quantity of landslide are not only closely related to the quantity of rainfall but also to the characteristics of intraday precipitation and pre-precipitation.
