Abstract 蒋家沟是一条规模巨大、暴发频繁、类型齐全、流态典型的暴雨型泥石流沟,为开展泥石流流态和流变的研究提供了良好的条件。本文试图从讨论泥石流的流变特性着手,研究各类泥石流的流态性质,分析影响泥石流流态的诸因素,阐明泥石流流态的时空变化,为建立泥石流所特有的流动模式提供论据。
Other AbstractThe debris flow body in the Jiangjia Ravine and its slurry body is of power law fluid with the starding static shear, in which watery debris flow is pseudo-Bingham fluid with the turbulent effect, viscous debris flow is Bingham fluid or Bingham fluid with slipping effect, plastic debris flow is pseudo-plastic fluid with the starding static shear.Debris flow state is an interim fluid state between sedimentladen flow (turbulent and lamellar flows) and plastic earth mass (wriggle and slip) i. e. turbulent flow,lamellar flow,wriggling flow, slipping flow and a spacial fluid state——undulatory flow.The debris flow state is decided by debris flow characteristics, the ravine bed conditions and debris flow amount at the upper reach. These factors is a variable at the different reaches and in differends stages, so that debris flow state is of variability too.
