DEFORMATION/DAMAGE/POST FAILURE ANALYSIS METHOD OF REINFORCED SOIL WALLS USING SPH METHOD

Abstract

 With the growing interest in risk-based design, the choice of analysis method to estimate deformation, damage, and failure of geotechnical structures is important. The authors aimed to develop a SPH analysis method for analysis of reinforced soil walls. The general approach is based on the framework of the existing SPH analysis method. The fill material is represented by an elasto-plastic model considering dilatancy, the reinforcement-soil region is represented by a composite material model, and the facing panels are represented by a rigid body. In order to verify the proposed method for deformation and damage analysis, a full-scale model loading test, carried out at the Royal Military College of Canada, was simulated. The applicability of the proposed method for failure analysis is also demonstrated by investigating the scenario of a reinforced soil wall with functional loss of foundation and facing panels. The analysis results show that the the proposed method can be applied for deformation and damage analysis and that it also provide useful information for failure analysis.
