以汶川地震极震区绵阳市安县高川乡泥石流为例,在对其爆发历史及相应降雨资料的详细调查、收集基础之上,研究了高川乡泥石流发生的临界雨量特征,得到了该乡泥石流临界雨量Ic-R关系式,进而建立了高川乡泥石流发生的降雨警戒模式,得到该乡泥石流发生不同几率下的警戒基准线,并验证了该警戒模式具有较高可信度,可用于研究区泥石流预警分析中。 Taking the debris flow in Gaochuan Township, Mianyang City, Mianyang City, as an example, the critical rainfall characteristics of debris flow in Gaochuan Township were studied based on the detailed investigation and collection of the eruption history and corresponding rainfall data. Rainfall Ic-R relationship, and then established the rainfall warning mode of debris flow occurred in Gaochuan Township, and obtained the warning baseline under different probabilities of debris flow in this village, and verified that this warning mode has high credibility and can be used in the debris flow in the study area Early warning analysis.
