| Abstract: | Underground roads are characterized with large volume and channel traffic.FEM is established by adopting CRCP + AC composite pavement in accordance with the mechanical characteristics of CRCP + AC and CRC.The thickness of AC layer and CRCP layer is calculated after the analysis of factors affecting the load stress,such as horizontal force,the contact conditions between different layers,modulus and thickness of surface layer,resilient modulus of subgrade,and stress absorbing layer.Finally,some suggestions fo... |
