泥石流颗粒级配倒置浅释

AN IMTERPRETATION ON INVERSE GRADING OF SOLID PARTICLES IN DEBRIS FLOW

泥石流固体颗粒级配倒置,影响流速垂线分布、流态与冲击力,是一个十分重要的问题。本文根据力学及流变学对泥石流固体颗粒级配倒置进行了解释,对于泥石流运动机理的认识是有裨益的。

The inverse grading of solid particles in debris flow effects the velocity distribution along the vertical the state of motion and the impulse on structure is an important problem. It's mechanism is interpreted by mechanics and rheoiogy in this paper which is useful in the understanding of mechanism of motion of debris flow.
