摘要

通过比较分析了邙山黄土和粉煤灰在25°陡坡、人工模拟降雨条件下的侵蚀特点.得到以下结论

不同介质不同雨强条件下的侵蚀小区

降雨初期径流量都较小

随着降雨时间的延长

径流量、产沙量逐渐增大;当降雨进行到-定时间段时

径流量、产沙量会出现激增点

此后径流量、产沙量急剧增加

经过-段时间后

径流量、产沙量达到相对稳定状态;在不同的下垫面介质和不同雨强条件下

侵蚀小区的径流量、产沙量激增点和它们达到稳定的时间有很大的差异

随着雨强的增加

激增点及稳定时刻都会大大提前;坡面产沙量激增点及相对稳定时间-般滞后径流量的激增点及相对稳定时间约1～3 min;粉煤灰基本上能在较小雨强条件下模拟出邙山黄土在较大雨强时才能体现出来的侵蚀特点。

Abstract

Through the analysis of the erosion characteristics of Mt.Mang loess and the coal ash on 25 slope

little runoff was found at the beginning of rainfall under the conditions of different materials and diferent rainfall intensities.As rainfall continued

runoff and sediment increased gradually and then reached sharply high values.After the process continued for a few minutes

they dropped to a steady state.The sharp value and steady time were very different under different materials and different rainfall intensities and occurred early when rainfall intensit y increased.Generally

the sharp value and steady time for sediment occurred 13 min less than runoff.In addition

the erosion characteristics of light coal ash are the same as those of loess under high rainfall intensity.
