摘要
本文根据动量守恒和质量守恒原理，研究建立了泥石流堆积过程数学模型，运用有限差分法求解数学模型。以此为基础，以云南东川市深沟为实例，分析评价了泥石流灾害的危险范围和程度，结合各类受灾体价值分布，进行了泥石流灾害破坏损失风险评价。
Based on the principle of momentum conservation and conservation of mass, this paper studies and sets up a mathematical model of the process of debris flow deposit and work out the model with numerical simulation method. Meanwhile, the paper analyzes and appraises scope and extent of danger caused by debris flow, and carries out an assessment of losses by debris flow disaster with Shengou flume in Dongchuan City, Yunan Province as an example.
