Abstract To obtain the cold soil of different soil layers in northwest China and the discrete element simulation parameters with contact components (Q235 steel), an accurate EDEM simulation model was constructed.The cold soil was divided into three layers, and Hertz-Mindlin (no slip) was used as contact model. The stacking angle test and straight shear test were used, and the significant factors were determined by the Packett-Burman method. The narrowing range was determined by the steepest climbing test,and the Box-Behnken response surface analysis method was used to determine the regression equation. The elastic recovery coefficient, the rolling friction factor and the static friction factor between different layers of soil particles were determined gradually.Through soil slip test and two-factor universal rotation center combination simulation test, the values of elastic recovery coefficient, static friction factor and rolling friction factor between soil particles and scrapers of different soil layers were obtained. The results show that the relative error is 5.78%, and the simulation parameters and research methods of layered cold soil calibration are verified.
