降雨型滑坡水文地质条件分类浅析
|
摘要
降雨型滑坡与降雨入渗及渗流过程密切相关。在分析、总结不同滑坡在降雨条件下的入渗、变形特征的基础上,针对降雨型滑坡的水文地质条件分类进行了分析,并根据降雨入渗形式和降雨运移形式进行分类。前者细分为表面入渗型和优势通道入渗型两种,后者细分为裂隙型、岩溶型和孔隙型,并对各分类下滑坡的滑动机理进行简单的分析。
Rainfall-induced landslides are closely related to rainfall infiltration and seepage processes. Based on the analysis and summary of the infiltration and deformation characteristics of different landslides under rainfall conditions,the paper analyzes the classification of hydrogeological conditions of rainfall-induced landslides according to rainfall infiltration and migration. The former is subdivided into surface infiltration type and dominant channel infiltration type,and the latter is subdivided into fracture type,karst type and pore type. In addition the sliding mechanism of each type is simply analyzed.
