DEM解析における要素定数の検討

抄録

The distinct element method (DEM) have the potential applicability for analysis of fissured rock structures and granular materials. Before its practical application, a suitable procedure for determining element constants should be developed.
Simple evaluations of element constants K and η by elastic contact theory and inelastic attenuation of rebounding, respectively, are proposed, and the results of laboratory tests, such as a free-fall rebounding test and Schmidt hammer test are described in detail.
Finally a slope stability of blocks are submitted to the DEM analysis and the relationships among the element constants K, η, φ_μ, the angle of inclination and the block dimensions are discussed.
