Abstract

A numerical simulation model based on the particle size composition of High Viscous Dredger Fill (HVDF) was established. Consolidation process of HVDF was in the action of Direct Drainage Vacuum Preloading (DDVP) and was in the Graded Vacuum Preloading (GVP), which was described the drainage consolidation characteristics of HVDF subject to the two drainage systems. The two methods of preloading were compared with different distance between two drainage boards. Both DDVP and GVP improved vacuum preloading velocity. But GVP was advantageous over DDVP in HVDF consolidation. The porosity of HVDF gradually become uniform in GVP. And it is suitable for HVDF consolidation to distribute probable time ratio and vacuum degree escaped from silting-up. So the laboratory experiments based on the results of numerical simulation explored the mechanisms of HVDF consolidation under GVP.
