Abstract
In this paper, a simulation for real-scale slope excavation experiment was reproduced using the SPH (Smoothed Particle Hydrodynamics) method. The method can treat large deformation problems because the method is based on the free mesh system. In addition, the constitutive models of geomaterials can be used directly. At first, slope stability analysis was carried out to validate the SPH method. The numerical results were compared with results of the safety factors provided by the Fellenius method. Then, a simulation for real-scale slope excavation experiment was carried out. All deformation processes, from the start of excavation to subsequent failure, were reproduced in the simulation. The numerical results obtained from the SPH method and the experimental results were compared. The SPH method was applied to excavation analysis, and the results demonstrated its applicability to the entire deformation process from the initial state to subsequent large deformations.
