摘要

以试验为基础

研究了泥石流入汇主河后淤积规律

主要探讨了淤积量及淤积分布问题。通过试验分析认为

泥石流入汇主河后的淤积量基本随流量比的增大而增大

就其淤积速率而言

有先增大后减小的变化规律。淤积量在流量比大约为0.5时出现峰值

在流量比为0.65时出现谷值

淤积量与流量比关系变化曲线以倾斜向上的直线为对称轴

呈倾斜向上的正弦波形。各工况下淤积范围基本不变

但试验中反映出

淤积范围有随交汇角增大而增大的趋势。

Abstract

Based on the experiment

deposit principle of debris flow when it confluence with the main river is studied. Deposit quantity and region is analyzed. According to the experiment

deposit quantity will increase with the increasing of discharge ratio. As deposit speed is considered

it will be first up then down. Deposit quantity will get the maximum value at discharge ratio of 0.5 and get minimum value at 0.65. The curve (relation between deposit quantity and discharge ratio) will be an uphill sinusoid. Deposit region will change little in all experiment conditions. As shown in the experiment

deposit region may expand with the increasing of the confluence angle.
