Abstract

工程堆积体在强降雨条件下极易发生严重的水土流失,成为某些建设项目主要的水土流失来源。为
了系统揭示高边坡工程堆积体的土壤侵蚀特点,在建设的3个坡度(24°,28°和32°)、宽5m、坡长20m的小
区上进行放水冲刷试验。结果表明,产流量、产沙量与放水流量、坡度之间存在线性正相关关系,即随着放
水流量、坡度的增大,产流量、产沙量在不断增大。临界产流放水流量和临界产沙放水流量均说明工程堆
积体下渗强烈。由于下渗强烈,流量较小时(30L/min),坡度对产流量的影响不明显。试验条件下产流量
和产沙量存在密切的幂函数关系,具体表达式是Ms=0.560 W0.886。

Other Abstract

Engineering accumulation bodies are prone to serious soil erosion under heavy rainfall and other
conditions,which becomes a major source of soil erosion in some construction projects.In order to systematically
discover the characteristics of soil erosion on steep slope of engineering bodies,souring experiments were carried out
on steep slopes of engineering bodies,with 3slope gradients(24°,28°and 32°),5mof slope width and 20mof
slope length.Through these experiments,we found that runoff and sediment yield showed positive linear relationships
with drainage flow and slope gradient.With the increases of drainage flow and slope gradient,runoff and sediment yield
also increased.Critical drainage flow rates of runoff and sediment yielding indicated the strong infiltration of engineering
accumulation body.Due to the strong infiltration,when the drainage flow was small(30L/min),effect of slope gradient
on runoff yield was not obvious.There was a significant power function relationship between runoff and sediment yield
under test conditions,and the expression was Ms=0.560 W0.886.
