Dependent Behavior

The combined effects of the rate-dependent behavior of both the backfill soil and the geosynthetic reinforcement have been investigated, which should be attributed to the viscous property of material. A nonlinear finite element method (FEM) analysis procedure based on the Dynamic Relaxation method was developed for the geosynthetic-reinforced soil retaining wall (GRS-RW). In the numerical analysis, both the viscous properties of the backfill and the reinforcement were considered through the unified nonlinear three-component elastic-viscoplastic model. The FEM procedure was validated against a physical model test on geosynthetic-reinforced soil retaining wall with granular backfill. Extensive finite-element analyses were carried out to investigate the tensile force distributions in geosynthetic reinforcement of geosynthetic-reinforced soil retaining wall under the change of loading rate. It is found from the analyses that the presented FEM can well simulate the rate-dependent behavior of geosynthetic-reinforced soil retaining wall and the tensile force of geosynthetic reinforcement arranged in retaining wall.

For the geo-grid reinforced retaining wall, the reinforcement mechanism of seismic behavior is unclear, and there is no reasonable standard for seismic design. A non-linear finite difference method which is based on Lagrange method was applied to analyze internal reinforcement force of geo-grid under different design parameters. The elastic-plastic model is simulated to backfill soil and foundation, and the coupled elastic parameters are used to describe the interaction of soil and geo-grid. The design parameters include geo-grid reinforcement spacing, reinforcement length, backfill soil stiffness, and thickness of panel. Some distribution characters and sensitive parameters to the internal reinforcement force of geo-grid were achieved, which will be helpful to the seismic design of geo-grid reinforced soil retaining wall with integral panel.
