Abstract
This study investigates the influence of dry density on the permeability characteristics and fine particle migration behavior of remolded granite residual soil through seepage erosion experiments.The results indicate that dry density significantly affects the evolution of soil permeability coefficient,which can be categorized into low dry density group(1.20-1.30 g/cm3),medium dry density group,and high dry density group.In the low dry density group,the permeability coefficient continuously increases with the increase of hydraulic gradient;the medium dry density group exhibits a three-stage trend of initial increase,subsequent decrease,and final increase;while the high dry density group shows a two-stage characteristic of initial increase followed by decrease.These findings reveal that dry density governs the evolution of permeability coefficient by regulating fine particle migration.关键词
