关于泥石流的研究,现已成为水土保持研究的中心课题.泥石流每年都在一些地方产生,并造成灾害.泥石流的产生条件、流动特性及堆积过程等应予阐明的事项很多,并急待求得研究成果.本论文是通过实验.研究泥石流变为推移的坡度、输沙形态及输沙量的成果.这种坡度在地形上是和沟谷出口直到冲积扇对应的,是泥石流的堆积和再侵蚀的场所.对于堆积和再侵蚀过程的模拟,虽然尚有若干应予解决的问题,但是这里论述的输沙形态和输沙量是其基础.
Research on debris flow has now become a central issue in soil and water conservation research, and debris flows occur in some places and cause disasters every year.Many issues to be clarified, such as the conditions of occurrence, flow characteristics and accumulation of debris flows, are urgently needed Research results.This paper is the result of experiments on the study of the change of the debris flow to the gradient of slope, sediment transport and sediment discharge.The slope is corresponding to the alluvial fan at the exit of the valley and topography, which is the accumulation and re-erosion of the debris flow For the simulation of the accumulation and re-erosion process, although there are a number of problems to be solved, the sediment transport and sediment load discussed here are the basis.
