Cemented coarse-grained soils have both the properties of coarse-grained soils and concrete. This paper used discrete element method (DEM) to simulate of the drained monotonic load triaxial tests of coarse-grained soils and cemented coarse-grained soils respectively, the microscopic parameters of numerical models were calibrated based on the tests. The characteristics of the cemented coarse-grained soils and the microscopic mechanism were analyzed. The results showed that, the cemented coarse-grained soils have the higher modulus and strength compared with coarse-grained with adding the 3% cement in the specimens and appear the significant strain softening after the stress reaches the peak value; the deformation of the soil particles,the friction between soil particles and the crack of the cement bond are the mainly internal factors.
