为研究裂隙对坡面流及土壤水分入渗的影响，通过染色示踪试验，对染色示踪图像进行二值化处理，提取出各像素点染色信息。对染色信息及试验数据处理得到径流量、土壤水分入渗量等参数，进而分析裂隙网络对入渗深度、染色面积、坡面流及土壤水分入渗的影响。结果表明，裂隙网络的存在减小了坡面径流系数，增大了降雨入渗系数；较无裂隙试验相比，50 mm/h 雨强下裂隙试验组平均径流系数减小了 0.42，降雨入渗系数增大了 0.53； 30 mm/h 雨强裂隙试验组平均径流系数减小了 0.15，降雨入渗系数增大了 0.38。裂隙网络的存在增大了剖面的入渗深度、染色面积；较无裂隙试验相比，50 mm/h 雨强下裂隙试验组平均入渗深度增大了 21.34 cm，平均染色面积增大了 36.0%；30 mm/h 雨强下裂隙试验组平均入渗深度增大了 5.70 cm，平均染色面积增大了 9.5%。
In order to study the effect of cracks on slope flow and soil water infiltration, the dyeing tracing test was used to binarize the stained image and extract the information of each pixel dyeing. The parameters of runoff and soil infiltration were obtained by processing the dyeing information and the experimental data, and then the effect of the fracture network on infiltration depth, dyeing area, slope flow and soil moisture infiltration was analyzed. The results show that the existence of fissure network reduces the slope runoff coefficient and increases the coefficient of rainfall infiltration. Compared with no fissure test, the average runoff coefficient of the fissure test group decreases by 0.42 under 50 mm / h rainfall intensity, The coefficient of permeability increased by 0.53. The average runoff coefficient of 30 mm / h rainstorm fracture group decreased by 0.15 and the coefficient of rainfall infiltration increased by 0.38. The existence of fractured network increased the depth of infiltration and the area of dyeing. Compared with no-fissure test, the average infiltration depth increased by 21.34 cm and the average dyeing area increased by 36.0 %. Under 30 mm / h rainfall intensity, the average infiltration depth of the experimental group increased by 5.70 cm and the average staining area increased by 9.5%.
