摘要
结合台风产生的形成、特点,移动路线与强度,分析其对地质灾害的影响,地质灾害是地质因素-气象因素耦合作用的产物,暴雨持续天数、持续雨量、降雨历程、降雨强度等因素有显性的正相关,地貌特征、土层厚度、母岩特性和植被条件对降雨入渗引起变形斜坡体含水量、渗透压和表层位移等动态参数变化和相互影响呈隐性相关。
Influences from the typhoon formation,characteristic features,the moving path and the intensity on the geology disaster are analyzed here.The geological disaster is a geologic-climatic factor coupling function product.The rainstorm duration,the rainfall,the history and the intensity is significantly and positively correlated to the geology disaster.And the geomorphic feature,the thickness of soil layer,the parent rock characteristic and the vegetation condition has a recessive relation to the variation of the dynamic parameters caused by the infiltration,such as the deformation slope moisture content,the osmotic pressure and the displacement.
