摘要：

Based on theory of viscoelasticity and dynamics, the performance of dynamic stress intensity factor (KI) is discussed under vertical load with different vehicle velocity, rebound modulus and damping ratio by FEM simulation. The influence of KI with both horizontal and vertical loads is analyzed. The numerical results show that the value of KI decreased with increase of the vehicle velocity and the damping ratios. The value of KI increased rapidly with increasing of the base modulus. The peak point of the KI increased with both horizontal and vertical loads, which would influence the shear stress and tensile stress of the road.
