摘要
本文对泥石流现象的引发与预警,泥石流灾害减灾、预防及治理等相关问题做了研究。首先,我们对东川区蒋家沟泥石流产生的可能机理进行分析,建立了基于降雨增加土壤含水量,使土壤重力作用加剧,从而形成山体崩塌,进而发生泥石流现象原理的通用(General Model)模型(GM),并提出了土壤含水饱和度、摩擦因子系数、冲刷系数的合理定义。
On the foundation of the formation of mud-rock flow,this paper studies several issues in this field,including cause,forecast,prevention,damage control and disaster defense with model analysis.Firstly,this research analyses the possible formational mechanism of mud-rock flow in Jiangjiagou of Dongchuan region,and build the general formation model where rainfalls increase water content in the soil to increase the gravity effect of soil,which causes avalanche and mud-rock flow occurs.This research also provide...
