There are many historic masonry structures collapsed due to deformation and/or failure of their foundation ground, and then, it is demanded to investigate the deterioration mechanisms and the rational restoration methods based on the geotechnical engineering. In case of the Angkor ruin in Cambodia, buildings were constructed on the foundations consist of the man-made soil embankment and the masonry stones, so-called ‘ platform’. Therefore, to achieve the restoration ensuring structural stability, the bearing capacity characteristics of the masonry platform in various structural conditions should be investigated. In this paper, the bearing capacity analyses of the masonry foundation with different number of layers were carried out using NMM-DDA (coupled Numerical Manifold Method and Discontinuous Deformation Analysis) enhanced with the node-based uniform strain element, and the influence of the structural features on the ultimate load was discussed.
