摘要

[目的]探究坡长对黄土区工程堆积体产流产沙的影响，为生产实践中工程堆积体水土流失合理防控提供理论依据和技术支撑。[方法]在裸露的堆积体边坡上选取3个坡度（24°，28°，32°）5个坡长（4，8，12，16，20 m）进行野外模拟径流冲刷试验。[结果]24°，28°，32°坡面产流率和产沙率均随坡长的增加持续波动；4和8 m处坡面的产流率和产沙率之间相关性显著，12，16和20 m处坡面的产流率和产沙率间只有在32°时相关性显著；累积产流量和累积产沙量均随坡长增加而增大且符合幂函数关系；累积产沙量与累积产流量之间具有线性函数关系。[结论]坡长对坡面产流率和产沙率的影响因坡度而存在差异性；累积产流量、产沙量均随坡长的增加而增加。

Abstract

[Objective] The effects of slope length on the runoff and sediment yield of the engineering accumulating body were studied in order to provide theoretical basis and technical support for the reasonable prevention and control of soil and water loss in engineering accumulations in production practice.[Methods] Three slope (24°

28 °

32 °) and five slope length (4

20 m) were selected for simulated field test of runoff erosion on exposed engineering accumulating body.[Results] The runoff rate and sediment yield of 24°

28° and 32° slopes fluctuated with the increase of slope length. The correlation between the runoff rate and the sediment yield of the 4 m and 8 m slopes was significant

the correlation between the runoff rate and the sediment yield of the slope at 12

16 and 20 m was only significant at 32°. Cumulative flow rate and cumulative sediment yield had a power function relationship with slope length. The cumulative sediment yield and cumulative yield had a linear function relationship.[Conclusion] The influence of slope length on slope runoff rate and sediment yield was different due to different slope; cumulative runoff and sediment yield increased with slope length.
