| 摘 要： | 泥石流作为一种固-液混合而形成的地质灾害,其启动过程中必然存在着水与岩土体之间的相互作用。根据对太行山区泥石流形成的地形地貌、降雨、物源和人类活动特征等影响因素的分析,确定太行山区泥石流的崩滑动力和洪水动力两种启动类型。在此基础上,从水-岩系统耦合作用的角度,研究了太行山区泥石流形成过程中,洪水与固体颗粒之间彼此促进、相互制约的水岩化学作用、水岩物理作用和水岩力学作用,阐明了水岩相互作用对泥石流初始形成的促进机制,从而为泥石流启动预测预报体系的建立提供理论支撑。

| Abstract: | Debris flow,as a geological disaster,is a mixture of solid and liquid and water-rock interaction occurs during the formation process.Based on the analysis of several factors initiating debris flow in the Taihang mountain area,including the topography,precipitation,material source,and human activities,two types of debris flow initiating mechanisms are determined:the rock fall-landslide and flood.From the aspect of the water-rock coupling system,the chemical,physical,and mechanical interactions between the flood and solid particles during the formation of debris flow in the Taihang mountain area are investigated.Moreover,this paper illustrates the promotion mechanism of water-rock interaction on initiating debris flow,which can provide theoretical support for establishing a forecast model of debris flow. |
