摘要
With the rapid development of opencast mines, there is an increasing demand of extra-heavy duty vehicle for mines. The physical road structure model of vehicle SF31904 acting on the cement concrete pavement is established in this paper. The tensile stress in different situations about pavement thickness, subgrade stiffness, base rigidity and thickness was analysed using the ABAQUS finite element software. The recommended values about the cement concrete slab thickness are proposed and the factors affecting the stress are analyzed through this simulation analysis. The theoretical basis for design of the mine road was suggested.
