摘要

汶川地震后

震区泥石流物源类型在规模、数量与分布方式上与传统泥石流物源类型存在极大差别

传统统计泥石流动储量与总物源量的方法已不能满足目前震区泥石流工程设计的需要。因此

以研究区的48条泥石流流域内的崩滑体、沟道物源、坡面物源的体积（静储量）、面积、动储量数据为样本进行分析

利用Matlab软件对泥石流流域内崩滑体、沟道物源、坡面物源的体积与面积、静储量与动储量分别进行单因子回归分析

发现静储量与面积之间具有明显的幂函数关系

静储量与动储量之间分别具有明显的二次项、幂函数、三次项关系

从而建立泥石流动储量与总物源量的计算模型。

Abstract

There is great difference between the types of Debris flow material in earthquake-affected areas and the traditional material in scale

quantity and distribution after the Wenchuan earthquake.The method of traditional statistical material could not meet the needs of engineering design for debris flow currently.Therefore

this paper uses the data from field investigation in examining 48 debris flow gullies to find the volume

the area and the dynamic reserve of the avalanches landslide

the channel material and the slope material.The regression analysis of the avalanches landslide

the channel material and the slope material volume and area with dynamic reserve and the total amount of material source in debris flow basin is made by using the software Matlab.It is found that not only volume and area of the avalanches landslide

the channel material and the slope material and dynamic reserve and the total amount of material source of the channel material have an obvious power function correlation

but also the total amount of material source of the avalanches landslide and the slope material have an obvious quadratic term function and cubic function correlation with dynamic reserve.This model is established

which can predict the dynamic reserve and the total amount of material source of debris flows.
