摘要

Preloaded and prestressed (PLPS) reinforced soil method aims at substantially increasing the stiffness and decreasing the residual settlement of reinforced soil structures. The first prototype PLPS reinforced soil pier was constructed for a railway bridge in 1996. As a part of a research program to develop a methodology for predicting the time-dependent behaviour of such reinforced soil structures, one of three-component rheology models, named "New Isotach Model", is used to analyze the observed time-dependent (viscous) load-deformation behaviour of the PLPS pier during its preloading procedures.
