- 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.
