| 520 | _aThe full-scale test embankments, reinforced with steel grid, hexagonal wire mesh, and polymer grid, were constructed on soft Bangkok clay. This study deals with 3D numerical simulations of these reinforced embankments considering the plane strain and 3D embankment loading conditions using FLAC30 software of the finite difference method. First 3D numerical simulation of three pullout test with same combination of reinforcement and backfill soil for each embankment, such as steel grid and lateritic soil (Embankment 1 ), hexagonal wire mesh and Ayutthaya sand (Embankment 2), and polymer grid and weathered Bangkok clay (Embankment 3) are made to investigate the behavior of the soil-reinforcement interface. Numerical instability is observed in this pullout simulation and reduced by introducing the smaller element size and time step. The effects of Young's modulus of reinforcement, and the strength ratio and shear stiffness of soil-reinforcement interface element are also investigated. Next three full-scale test embankments are simulated by using the interface properties obtained from the simulation of pullout test. The properties of subsoil foundation, backfill soils, and reinforcements are mainly taken from the previous test results. The 3D loading effect can be clearly seen in all embankments. The effects of Young's modulus of reinforcement, the strength ratio of soilreinforcement interface, and the permeability of subsoil foundation are also investigated. | ||
