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。
After the Wenchuan earthquake, the source types of debris flow in the earthquake area differ greatly in their size, quantity and distribution from the traditional types of debris flow sources. The traditional methods for calculating the amount of debris flow reserves and the total amount of supply can not meet the needs of current debris flow engineering design Need. Therefore, the data of the volume of collapse bodies, channel sources and slope provenance in the 48 debris flow valleys in the study area are analyzed. The Matlab software is used to analyze the landslides in the debris flow basin One-factor regression analysis of the volume, area, static reserve and dynamic reserve of slide body, channel source and slope source shows that there is an obvious power function relationship between static reserve and area. Between static reserve and dynamic reserve, Respectively, with significant quadratic term, power function, the relationship between the three terms, so as to establish a calculation model of debris flow reserves and total amount of material.
