摘要
通过室内模型试验研究 ,对不同规模的水石流、稀性泥石流、黏性泥石流在堆积扇上输沙特征进行了研究。试验结果表明 ,不同类型泥石流在堆积扇上表现出不同输移、冲淤、含沙量演变特征 ,在堆积扇不同部位泥石流输沙特征也有差异。
The transporting characteristics of debris flow of different types (viscous, diluent and water stone) at Guxiang accumulation fan in the Tibet Autonomous region are studied by indoor model tests. The reseach focuses on the transportation of debris flow, the erosion and deposition of debris flow fan, the changes of sediment concentration. The results show that they are controlled by the characteristics of debris flow body and the longtudinal slope of accumulation fan.
