体。通过人工降雨试验,设计4 种降雨强度( 1. 0~ 2. 5 mm/min) 和3 种砾石含量( 10%~ 30%) 完全组合。采用灰色关
联度分析法,评估坡面水力参数与土壤剥蚀率之间的关联度。结果表明: ① 在试验条件下,坡面水流功率与土壤剥
蚀率呈幂函数关系; ② 当堆积体砾石含量一定时,以降雨强度为变量能反映堆积体坡面水力参数与土壤剥蚀率之
间的关联度; ③ 当降雨强度一定时,大雨强下( ≥1. 5 mm/min) 堆积体砾石含量不宜作为灰色关联度分析的变量。

Other Abstract

The relationship of sheet-flow erosion and hydraulic factors on tapered engineering spoil bank slopes was
investigated by laboratory simulation of scattered,tapered spoil banks in the red soil region of northern Jiangxi Province,
China. An artificial rainfall experiment was conducted using a complete combinatorial design of four rainfall intensities
( 1. 0—2. 5 mm/min) and three gravel contents ( 10%—30%) . Gray relational analysis was performed to assess
the correlation between hydraulic parameters and soil detachment rate on the spoil bank slopes. The results
showed that: ① Under the experimental conditions,there was a power function relationship between stream power and
soil detachment rate; ② With a fixed gravel content of spoil bank,the analysis with rainfall intensity as a variable
could reflect the correlation between hydraulic parameters and soil detachment rate on the spoil bank slopes; ③ Under
a fixed rainfall intensity of greater than 1. 5 mm/min,it was unsuitable to use the gravel content of spoil bank as a
variable of gray relational analysis. In conclusion,stream power is the optimal hydraulic parameter to describe the erosion
process of tapered engineering spoil banks,and it can be used to construct physical models of spoil bank erosion
in the red soil region of northern Jiangxi.
