Abstract: This paper, aiming at mitigating the hazard of Chulugou debris flow, makes a detailed survey on it and analyzes its formation features and dynamics, which is prone to occur, large and at its developing stage with a circle of 50 years, accumulating a total volume of loose material 22915k cubic meters in the gully, of which 2168k could contribute to debris flow. Its speed at the mouth of gully is 64 m/s.The flux of onceevery-50-year occurring debris flow reaches1067 m3/s, with a total volume of 308 k cubic meters, of which solid amounts to 130 k. According to terrain, loose, formation area, flowing path, devices are installed in different locations to carry out the survey, including 3 rain gauges, 2 mud meters and 2 moisture meters, on debris flows occurrence,converging,and flowing,offering data in forecasting debris flow and references to prevent and handle debris flow.

摘要: 为了减小出路沟泥石流造成的危害,对出路沟泥石流进行了详细调查。通过分析和研究出路沟泥石流的形成特征和动力力学特性,得知出路沟为中易发、特大型泥石流沟,处于发展期,发生特大型泥石流周期为50 a,沟内松散物储量约为22915×10^4 m3,可为泥石流发生提供的物源总量为2168×10^4 m3,沟口泥石流的流速达64 m/s,50年一遇泥石流洪峰流量为1067 m3/s,泥石流总量为308×10^4 m3,固体物质总量约为13×10^4 m3。根据地形、松散物分布、形成区、流通区位置,选择不同设备和位置开展监测,共安装了3台动雨量计、2台泥位计和2台含水率监测仪。通过对泥石流发生的产、汇、流条件进行研究,可为同类地质环境泥石流预测预报提供数据支撑,更好地为泥石流防治提供参考和建议。
