摘要:
为探讨黄土中水分入渗过程的定量描述方法,开展了天然与重塑黄土的染色剂溶液土柱淋漓试验,对溶液入渗过程中土柱的电阻率变化及淋漓试验结束后不同深度横剖面染色区形态进行了定量分析.试验结果表明:相同入渗条件下,天然黄土电阻率随时间降低程度较重塑土高,而重塑黄土的电阻率呈阶段性减小.由于大孔隙结构的存在,水分在天然黄土中较重塑土能入渗至更深处,并且天然黄土横截面染色区面积比随深度降低程度较重塑土小.染色区边界分形维数在重塑黄土中随深度单调增大,而在天然黄土中则先增大后减小.
Abstract:
To study the quantitative characterization methods of moisture infiltration in loess,column leachingtests with dye tracer solution were conducted.The variation of electrical resistivity of loess during moisture in-filtration and the morphology of cross - sectional stained area of different depthes after infiltration were quanti-tatively analyzed.The test results indicate that under the same condition of moisture infiltration,the electricalresistivity decrease of natural loess with time is higher than that of remolded loess,while the electrical resistivi-ty decrease of remolded loess possesses staged property.Due to the existence of macropores,the moisture caninfiltrate into natural loess deeper than remolded loess,and the stained area ratio decreases less in natural lo-ess than in remolded loess.Generally the fractal dimension of stained area boundary increases monotonously inremolded loess,but increases first and then decreases in natural loess.
