Other Abstract在四川境内成昆铁路沿线野外考察的基础上,确定了泥石流数据库预测预报系统的各种参数,提出了泥石流沟谷是否具备暴发泥石流的碎屑物量的判别式:比值=碎屑物聚集总量/暴发泥石流的碎屑物量最低标准。当比值≥1时,具备了暴发泥石流的碎屑物条件,应作出可能暴发泥石流的预测。同时还根据泥石流暴发的降水资料,确定了暴发泥石流的降水量标准为日雨量≥50毫米。根据暴雨信息可作出泥石流预报。 ; On the basis of investigation on debris flow along Chengdu-Kunming Railway in SichuanProvince,the debris accumulated volume and aggregated volume,and the parameters of effectiyefactors have been taken out according to debris volume. Here, the debris accumulated totai vo(?)= beginning value of debris accumulated volume+debris accumulated volume of (?)from next year. The debris aggregated total volume = beginning value of de(?)is aggregated volume+debris aggregated volume of every year from next year. At the sometime,the discrinci-nant determined whether the debris volume in debris flow gullies causing debris flow has been put out. Ratio = debris aggregated total volume/minimun debris volume for causing debris flow. When ratio < 1 ,the debris volume can not arouse debris flow;.when ratio≥1 .debris flow will occur.Based on the analysis of data on debris flow occurrence and relative rainfall,the daily rainfall of hard rain causing debris flow should be≥50mm.According to preestimate and forecast, the occurrence of debris flow should be predicted while daily rainfall in the hard rain area ≥50mm.
