Keyword泥石流 浓度 含沙量 滑坡体 预测
Abstract泥石流是山区界于夹沙水流与滑坡体之间的固、液、气混合流体。它既不同于夹沙水流,又不同于滑坡体,但同时兼有夹沙水流和滑坡体的某些特性的特殊流变体。泥石流体的浓度随着含沙量的增加而逐渐增大,当含沙量达到或超过380kg/m3时,其流体的物理力学性质和结构就发生质的变化,这是泥石流体最基本、最重要的物理特性之一。而暴雨泥石流输沙年际变率的旋回特性,可为暴雨泥石流中、短时间尺度的预测研究探索一条新路。
Other AbstractDebris flows are the mixture of soil,waterand air between sandy flood and landslide.Debris flow are specially rheological body,they have the some special properties of sandy flood and landslide.Unit weights of debris flows increase with sediment concentration in the fluid,therefore it is one of the most important and basic physical properties.The cycle property of the annual transported sediment by rainstorm debris flows,it can seek a new idea pradicted rainstorm debris flow hazards.
