摘要
对牧场沟泥石流的动力特性进行了预测,认为该沟可形成中小规模泥石流,可提供的物源量约14×104m3。按周期50年一遇算,峰值流量为58.43m3/s,泥石流体冲击应力达6.52×104Pa,单块最大冲击力可达199.74×104N,发生一次泥石流总量为18510m3,一次泥石流冲出的固体物质总量为6571m3。
The dynamic characteristics of Muchang valley is forecasted. The valley can form small and medium-sized debris flow, and the availability of the source is about 14×10^4 m^3 . If we calculate according to 2 % frequency of the debris flow, the discharge peak value is 58.43m^3/s, the dash power of whole debris flow is 6.52×10^4Pa, the largest single block impact is 199.74×10^4N, total debris flow volume is 18 510m^3 , the gross amount of solid material is 6 571m^3 in one debris flow.
