Modeling suffusion of ideally gap‐graded soil

A novel framework for describing suffusion in cohesionless soil, incorporating ideally gap-graded is presented this paper. The key assumption of the proposed simulation that an erodible particle flow induced primarily by drag force. multiphase seepage-soil phenomena conducted based on framework. validity method checked through a past laboratory experiments, which variation grain size distributions grasped sieve analysis. primary results show cumulative fines loss; therefore, comparison loss mainly discussed research. In addition, discussion given two different parameters affecting erosion behavior, namely p − v l u e $p - value$ tortuosity function, T ( ∅ ) $T( \emptyset )$ , and clogging relaxation time, β c o g ${{{\beta}}_{clog}}$ . ratio actual path distance between its ends, while time parameter considers bottleneck. numerical provides good correlation with experiment, 3 highest value geo-material. Moreover, each also confirm smaller particles will be fully eroded earlier than larger ones, slowly become detached from soil mass.
