DYNAMIC TEST OF RIGID BLOCKS AND PARAMETER STUDY IN DYNAMIC ANALYSIS OF DISTINCT ELEMENTS
刚块动力试验与离散元法动力分析参数选择的研究

The relationship between static and dynamic friction coefficients of the rigid blocks with smooth surfaces has been studied preliminarily by means of a dynamic test of rigid blocks in this paper.The coincidence betwween the testing results and the numerical calculation results is to verify the distinct elementmodel.Besides the selection of the parameters used in the dvnamic analysis of the distinct elements hasbeen also studied,and some suggestive opinions for engineering calculation and analysis were obtaine.
