| 摘 要： | 贵州省望谟县北部2011年6月6日普降暴雨(200年一遇)并引发大规模泥石流灾害,给当地居民生活及交通造成严重损害。通过分析打易镇打便沟泥石流的现场调查资料,从物源、地形、降雨等方面分析了泥石流的成因,研究了泥石流的灾害特征和形成机理,对流域内滑坡型泥石流提取重要地形因子进行统计分析,得出了泥石流暴发的最小滑坡面积比例并拟合出临界暴发曲线,为泥石流灾害的预测和防治提供了参考。

| Abstract: | On June 6, 2011, the northern areas of Wangmo county in Guizhou Province appeared rainstorm and led to breaking out a large scale debris flow, which the disaster caused serious harm for local residents and traffic. Though the analysis of field investigation data of Dabian debris flow, this paper analyzes the causes of this debris flow from the aspects of topography, materials and precipitation and studies its disaster characteristics and formation mechanism. Finally, we extracted important topographical factors of landslide-debris flow in the basin to conduct statistical analysis through which we fit a critical curve and minimum landslide area ratio of breaking out debris flow. Therefore, it provides reference for prediction and prevention of debris flow disasters. |
