ABSTRACT

The paper presents an analysis of granular pile reinforced ground with in situ soil undergoing creep. The variations of settlement of the reinforced ground, the load sharing between the GP and the in situ soil, the stress concentration ratio, shear stress, void ratio versus log effective stress, etc., with time and stiffness factor are estimated and presented. Results indicate that the in situ soft ground gets unloaded due to creep, becoming lightly overconsolidated, another beneficial aspect of treating soft soils with granular piles. A new phenomenon, not unlike the pseudo-preconsolidation effect proposed by Bjerrum, is identified.
