| 摘 要： | 八一沟泥石流位于汶川"5.12"大地震极重灾区四川省都江堰市,是一条典型的沟谷型泥石流。本文在分析八一沟泥石流沟流域和泥石流基本特征的基础上,首先对形成泥石流的地形、水源、物源三个基本条件进行了深入论述,接着详细计算了泥石流的重质、流速、流量、冲出量等动力学参数,然后分析了泥石流的发展趋势,最后根据泥石流危险性和被保护对象的重要性,并提出了防治建议。

| Abstract: | The debris flow in Bayi gully was a typical gully debris flow,which was located in Dujiangyan County in Sichuang Province and heavily hit by Wenchuan May 12 Earthquake last year.According to the basic features of the valley and the debris flow,formation conditions of the debris flow,like topography,water source and sediment source,were firstly analyzed.Then dynamic parameters,including bulk density,flow rate,flow capacity and sediment flush-out were calculated.Finally,the development trend of the debris flo... |
