摘要

基于大量试验观察及数据分析研究，揭示了泥石流固相在浆体中的沉降规律。研究影响固相在泥石流浆体中沉降的三个主要因素，分析了各个因素影响泥石流固相沉降的根本原因。泥石流固相在浆体中沉降过程中可分为三个阶段，首先为初。始阶段，继而为快速沉降阶段，最后呈减速沉积阶段，并对各个阶段的沉降过程作了详细的分析。其中浆体粘度、固相质量和附加孔隙压力对固相在泥石流浆体中的沉降规律存在着至关重要的影响。

Abstract

In this paper

according to the study on a great number of experiments and data analyses

the sedimentation rule of solid particles in debris flow is set up. Three main factors that influence the particle sedimentation in debris flow were studied; the basic reasons to influence the particle sedimentation were analyzed. The particle sedimentation in debris flow could be divided into three stages

e. the starting stage

the quick sedimentation stage and the accumulation stage

and detailed analysis on the sedimentation process each stage was made. The liquid viscosity

particle quality and additional water pressure have an important role on the sedimentation rule of the particle in debris flow.
