Numerical Simulation on Mechanism of Soil Retaining Wall Reinforced with H-V Inclusions by DEM

Soil reinforced with horizontal-vertical(H-V) is a new concept of reinforced soil.A series of laboratory model tests of soil retaining wall reinforced with H-V inclusions were investigated and the particle flow code(PFC),based on the discrete element method(DEM),was used to simulate the model tests.The facing displacements and lateral earth pressures acted on vertical elements from PFC numerical simulations were compared with the results of model tests.Meanwhile,the mechanism and failure surface of soil retaining wall reinforced with H-V inclusions were investigated by the displacement and stress field of PFC ball units.
