摘要
以云南省东川市深沟泥石流堆积区为研究对象,根据深沟可能爆发泥石流灾害的区域范围、规模、性质和介质特征,按爆发20年一遇(频率5%)和100年一遇(频率1%)的泥石流灾害预测规模,运用数值模拟方法模拟了泥石流爆发历时过程的堆积运动特征及空间分布形态;分析了不同规模泥石流堆积运动过程中,泥石流堆积厚度及堆积运动速度在空间上和时间上的变化发展趋势.
With the example of Shengou flume in Dongchuan of Yunnan Province, the dynamic process and space appearance of debris flow deposit were studied in the case of the debris flow disasters every 20 years (5% frequency) and every 100 years (1% frequency), using numerical simulation method. The debris flow deposit thickness and speed characteristics on the space are analyzed in different times.
