滑坡等地质灾害频发制约了我国经济的发展,对滑坡的形成机理的研究已广泛开展。滑坡的产生受地质等因素的影响,而其中一个外部动力就是降雨,尤其是久雨和暴雨,常常诱发滑坡的产生。从已发生的滑坡分析入手,结合降雨特征,剖析了降雨对滑坡的诱发作用,得出应加强对易发滑坡等地质灾害地区的降雨监测,为滑坡的预报预警提供参考。
The frequent occurrence of geological disasters, such as landslides, has restricted the development of our economy and the research on the formation mechanism of landslides has been carried out extensively. The landslide is affected by the geology and other factors. One of the external forces is rainfall, especially heavy rain and heavy rain, which often cause landslides. Starting with the landslide analysis that has taken place and combining with the rainfall characteristics, the inducing effect of rainfall on the landslide has been analyzed. It is concluded that the rainfall monitoring should be strengthened for the landslides and other geological disasters prone to develop and provide a reference for the landslide forecast and warning.
