Structural Analysis of Heavy Haul Road in Mining Area Based on ANSYS
Journal: Architecture Engineering and Science DOI: 10.32629/aes.v7i1.5038
Abstract
Mining haul roads are subjected to extreme axle loads and frequent traffic, leading to premature deterioration of conventional pavement structures. To enhance load-bearing capacity and service life, this study proposes an innovative composite reinforced concrete pavement system combining C40 reinforced concrete with roller-compacted concrete (RCC). A three-dimensional finite element model incorporating dowel-joint mechanisms was developed using ANSYS software. Numerical simulations were performed under three critical loading conditions — slab corner, longitudinal joint edge, and transverse joint edge — to comparatively analyze deflection patterns and stress distributions between the proposed composite structure and conventional asphalt pavement. Results demonstrate that the reinforced concrete pavement exhibits substantially lower deflection values, confirming superior overall stiffness. The slab corner was identified as the most critical loading position, exhibiting both maximum deflection and peak stress concentrations. Furthermore, dowel bars effectively facilitated load transfer, reducing maximum compressive stress in the loaded slab by up to 26.8% and significantly improving stress distribution homogeneity. These findings validate the structural advantages of the proposed reinforced concrete system for mining heavy-haul applications and provide theoretical support for optimized engineering design.
