降雨诱发滑坡分析
|
摘要
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。
An increasing of disasters such as landslides influence the development of China's economy. The research on landslide mechanism is under taken widely. One of the influencing factors of landslides is rain-fall, especially the lasting rain and rainstorm, which are easily induced landslides. The article analyzes the effect of rain-fall inducing landslides, based on the statistics of happened landslides and the characters of rain-fall, leading to a conclusion that rain-fall monitoring in landslide area should be enhanced in order to provide the reference of predicting landslides.
