| 中文摘要 | 泥石流的运动流型与流态是研究泥石流运动力学的重要内容。以云南东川蒋家沟泥石流运动观测为例,对阵流型、连续型、复合型三种流型及相应的流量过程特征进行了分析;借鉴水力学的流态理论,对天然沟遭中泥石流的流动状态(即层动流、波动流现象)进行了探讨分析,指出在一阵流动过程中也会出现几种不同流态特征。 |
| 英文摘要 | The flow pattern and regime of debris flow motion is an important aspect in research on motion mechanics of debris flow. Research on this aspect is contributive to a deep understanding of basic characteristics of .debris flow, establishing of motion physical and mathematical models and serving to debris flow prevention and control. Based on observed data of debris flow in Jiangjia Ravine at Dongchuan, Yunnan Province, three flow patterns (gustiness continuous and mixed flows)and characters of relative discharge processes in motion are analysed in this paper. And then the flow regime of debris flow in the natural channel is observed and analysed,especially laminar and fluctuating flows,with reference to the flow regime theory of hydraulics. For example,in a typical gustiness flow, there are varied flow regimes such as strong turbulent, week turbulent, fluctuating, laminar and slip flows and varied characters of relative flow velocity. |
