Based on the principle of potential energy and the Base force element method,the meso-mechanical properties of rubber con-crete are analyzed.Based on this,a random circular aggregate model of rubber concrete is established,which simulates the failure process of rubber concrete under uniaxial static compression,and analyzes the failure mechanism.The influence of different rubber content on the compressive strength of rubber concrete was studied.The numerical simulation results show that the change of stress and strain of rubber concrete under uniaxial compression is less affected by the random distribution of aggregate,and the compressive strength decreases signif-icantly with the increase of rubber content.Compared with physical tests,it is found that the meso-damage model can well simulate the compressive strength and cracking process of rubber concrete,which provides a new way to analyze the meso-mechanical properties of rubber concrete in the future.
