Experimental investigation on evolution process of suffusion in gap-graded cohesionless soil
Yantu gongcheng xuebao, 2023 The suffusion involves selective erosion and gradual migration of fine particles through the voids of soil skeleton formed by coarse particles under seepage flow. As a result, redistribution of soil skeleton stress and deformation of soil may be induced.
