樱桃沟泥石流位于汶川“5·12”大地震震中北川县,是一条典型的沟谷型泥石流。本文在分析樱桃沟泥石流沟流域和泥石流基本特征的基础上,对形成泥石流的地形、水源、物源等基本条件进行了论述,并基于动力学原理,详细计算了泥石流的重质、流速、流量、冲出量等动力学参数。结构表明，樱桃沟泥石流的流体密度为1.686 t/m3，流速为6.06 m/s,大块石的运动速度为6.45 m/s，泥石流整体冲压力为35.56 kPa，泥石流的最大冲起高度0.72 m,爬高1.15 m，弯道超高0.41 m。笔者以期为正确设置泥石流防治工程提供理论依据。

The debris flow in Yingtao gully is a typical gully debris flow, which is located in Beichuan County,"5. 12"Earthquake epicenter, Sichuan Province. Based on the basic features of the valley, the characteristics of the debris flow and forming conditions like topography, water source and sediment sources, are firstly analyzed. Then according to the dynamic parameters, the bulk density, flow rate, flow capacity and sediment flush-out, are calculated. It is suggested that the fluid dense of debris flow is 1.686 t/m3,flow rate is 6.45 m/s, whole impact force is 35.56 kPa, maximum surge wave height is 0.72 m, debris flow climb-up is 1.15 m, super elevation in bend is 0.41 m. The results can offer theory basis for setting debris flow control structure reasonably.
