Abstract

If there exists a highly compressible material between the backfill soil and a retaining wall, the backfill soil approaches the active state even without any wall displacement. In this paper, this mechanism has been evaluated through a field test and its numerical simulation. Highly compressible tire derived geosynthetics (tire chips) was used as cushion in the trial testing. In the numerical simulation, the modified Cam clay model with super-subloading yield surface and rotational hardening (SYS Cam clay model) was used. The earth pressures for both the backfill conditions (conventional sandy backfill and backfill with cushion) were calculated, and the pressure reduction mechanism was clarified.
