The Influence of Fracture Network on Overland Flow and Water Infiltration in Soil
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雨强裂隙试验平均径流系数减小了0.…查看全部>>
This paper studied the impact of fracture network on overland flow and water infiltration in soil using dye tracer.By digitizing the two-dimensional dye images,we calculated the parameters related to runoff volume, infiltration volume in the absence and presence of the soil fracture network respectively.The result indicated that compared with the non-fractured soil,the fracture network reduced surface runoff coefficient and increased rain-fall infiltration c…查看全部>>
