摘要

[目的] 探析红土崩解特性和泻溜侵蚀发生的关系，为坡面治理提供理论依据。[方法] 测量泻溜边坡坡度、坡积体休止角等基本参数，试验测定红土团聚体特性及干湿交替条件下崩解过程，分析泻溜侵蚀地区发生泻溜侵蚀的边坡条件、红土水稳性团聚体稳定性和崩解特性的变化情况。[结果] ①边坡坡度和休止角是泻溜侵蚀发生的控制性因素之一。黄土台塬区泻溜边坡坡度40°以内很少发生泻溜，大于80°大大减弱。红土与泻溜坡积体自然休止角范围为25°～36°。②红土团聚体绝大部分为非水稳性团聚体，团聚体稳定性差，因此遇水极易崩解从而造成泻溜侵蚀的发生。红土团聚体干筛平均质量直径MWD与几何平均直径GMD分别为2.16 mm，1.37 mm，湿筛平均质量直径MWD与几何平均直径GMD分别为0.51 mm，0.25 mm，团聚体破坏率PAD为57.66%，分形维数D为2.96，ASI是转移矩阵法中表示团聚体总体稳定性的参数，红土ASI为1.75。③干湿交替通过减小红土崩解程度从而减弱泻溜侵蚀的发生。自然状态条件下红土崩解程度最大，最大崩解指数为81.79%

平均崩解速率为51.03 g/min；干湿交替条件下红土崩解程度较自然状态减小；不同干湿交替条件之间红土最大崩解指数不同但差异性不显著。④红土平均崩解速率与泻溜坡积体休止角、泻溜边坡坡度与ASI呈极显著正相关关系(p＜0.01)。[结论] 红土崩解特性与泻溜侵蚀的发生有密切联系

干湿交替通过减小红土崩解程度从而减弱泻溜侵蚀的发生。

Abstract

[Objective] The relationship between laterite disintegration characteristics and the occurrence of slumping erosion was investigated in order to provide a theoretical basis for slope management. [Methods] The basic parameters of slumping slopes such as slope gradient and angle of repose were measured; the characteristics of laterite agglomerates and the disintegration process under alternating wet and dry conditions were experimentally determined; and the conditions of the slope

stability of laterite water-stable agglomerates

and changes of the disintegration characteristics of the slumping erosion area were analyzed. [Results] ① Slope gradient and angle of repose were two factors that influenced the occurrence of slumping erosion. Sloughing was unusual in loess plateau areas with slope gradients of 40° or less and was considerably weakened by gradients greater than 80°. The natural angle of repose between red soil and slumping slopes varied from 25° to 36°. ② Most of the laterite agglomerates easily disintegrated when exposed to water because they were non-hydrostable and had weak stability

resulting in sloughing and erosion. The average mass diameter (MWD) and geometric mean diameter (GMD) of the laterite agglomerates were 2.16 mm and 1.37 mm for dry sieve and 0.51 mm and 0.25 mm for wet sieve

respectively. The percentage of agglomerate destruction (PAD) was 57.66%

with a fractal size D of 2.96. aggregate stability index (ASI) is a metric that represents the overall stability of agglomeration in the transfer matrix method

and the red clay ASI in this study was 1.75. ③ Dry-wet alternation reduced the rate of slumping erosion by reducing laterite disintegration. The highest disintegration index was 81.79%

and the average disintegration rate was 51.03 g/min. The disintegration degree of the laterite was lowered under the dry-wet alternation condition compared to under the natural state. The maximum disintegration index of the laterite varied between different dry-wet alternation circumstances but the difference was not statistically significant. ④ Laterite disintegration rates were favorably linked with the angle of repose

slope gradient

and ASI (p＜0.01) of the slumping erosion. [Conclusion] Laterite disintegration properties are directly related to slumping erosion

and dry-wet alternation reduces the rate of slumping erosion by reducing laterite disintegration.
