摘    要:琉璃河泥石流位于河南省商城县东部的苏仙石乡,是一条典型的沟谷泥石流.本文在分析琉璃河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密度、流速、流量、冲出量等动力学参数.结果表明,琉璃河泥石流的流体密度为1.47 t/m3,泥石流峰值流量为29.3 m3/s,泥石流流速为4.94 m/s,大块石的运动速度为4.0 m/s,泥石流整体冲击压力4.86 Pa,泥石流的最大冲起高度1.24 m,爬高1.99 m.动力学参数计算结果较为可靠,可指导泥石流防治工程设计工作.

Abstract:Liuli River is a typical valley-shaped debris flow,located at Suxianshi Town,eastern of Shangcheng county,Henan province.On the base of analysis of valley-shaped and basic feature of Liuli river debris flow,we hereby discussed the basic condition of terrain,water source and material source of the forming debris flow.Ac-cording to the dynamic principle,we have calculated the kinetic parameters such as density,speed,flowrate and output rate.The result shows that debris fow density is 1.47 t/m3,peak flow rate is 29.3 m3/s,speed is 4.94 m/s,rock block velocity is 4.0 m/s,whole impact pressure is 4.86 Pa,max impact height is 1.24 m and runup 1.99 m.
Keywords:Liuli River  debris flowgeological characteristics  dynamics feature
