Finite Element Analysis for Mechanism of Geonets-Soil Interaction

Finite element program is developed to investigate the “bump” mechanics model at bridge approaches .After examining the character of stresses and displacements within the backfill behind bridge abutments,mechanism of geonets-soil interaction and soil stabilization is obtained.Results from this study have been checked by in situ measurement and model test.Theoretical foundation is provided to widely use geonets.
