Tillage soil is a typical discrete particulate material, and it is the key of soil analysis of dynamic changes that the simulation for the generation and fracture of soil agglomerate with adhesive particle DEM. In this paper, we introduced bond model add to existing dry granular discrete element contact mechanical model of soil to express water adhesion, builded wet granular soil contact mechanics model. Through the soil specimen uniaxial compression test method for calibrating the model bonding parameter. In EDEM software, using the wet granular soil contact mechanical model which has been established to simulate the soil uniaxial compression test, and the simulation results were compared with the experimental results. As results show, the compression curves of simulation and experiment are in good agreement, and these two curves both increase linearly to a peak, followed by decreasing smoothly. The compression strengths for experiment and simulation were 33.68N and 32.66N respectively, and the simulative strength is 3% lower than that of experiment.
