Design chart for prefabricated vertical drains improved groundn (reference no 2869)

摘要

In this study, an interconnected design-chart is developed to design prefabricated vertical drain (PVD) improved ground taking into account the effect of the following factors on the radial consolidation rate where the case of uniform subsoil is assumed: (i) soil permeability and compressibility changes during the consolidation process, (ii) transition smear zone with hydraulic conductivity varying linearly, (iii) time dependent loading. The Finite Element Method (FEM) was used to solve the gene
