Numerous studies on sandy soil using DEM have been conducted, but sandy soil alone is insufficient under disaster area and extreme environments. However, simulators of autonomous construction robot mainly target sandy soil, and few studies targeting other soils and materials. In this study, a numerical analysis using cohesive soil and rubble in addition to sandy soil was performed using DEM. As a results, it was possible to express the cohesive of the soil and perform excavation analysis. In addition, for wood rubble, it was possible to perform simulation using wood rubble model using parameters decided in three-point bending test.
