摘要/Abstract

摘要： A two-dimensional discrete element code, particle flow code (PFC2D), is employed to investigate foundations reinforced with horizontal-vertical (H-V) inclusions. The initial states and loading processes of both unreinforced and H-V reinforced foundations are simulated by PFC2D method. The interface between particles and reinforcements, and the reinforcement mechanism of the H-V reinforced foundations are studied through stress distribution graphs, displacement vector graphs and contact force graphs. The simulation results demonstrate that the vertical elements of the H-V reinforcement keep the particles from being displaced under the applied load. The H-V reinforcement can distribute the load uniformly over a wider area, thereby improving the bearing capacity of soil foundation.
