    • Abstract
  • The single wheel load of vehicle is simplified as a uniform circular pressure acting on the road surface, then an integral solution method for calculating the induced stresses in subsoil due to a single moving wheel load is proposed based on the theoretical solution of Eason. An integral program for the proposed integral solution is coded so as to numerically evaluate the induced dynamic stresses. The cases of elastic half-space solid subjected to single wheel load with different acting radii and moving velocities are analyzed by the program. The calculated results reveal that the effect of acting radius and moving velocity on induced stresses depends on the depth of the soil element, and the distribution curves of induced dynamic stresses can be normalized to be one group of curves. The induced dynamic stresses due to a group of wheel load are evaluated using the superposition method. The effects of stress superposition and the moving velocity are more significant for deeper soil elements in subsoil, which results in complicated stress paths.
