Abstract

This study deals with the numerical simulation of the vibration level, L10, which is required to predict the traffic-induced vibration. First, the unit pattern of vibration level is developed on the basis of the analytical solution for ground vibrations generated by a vehicle model, which moves unilaterally on the surface of an elastic half space. Secondly, the arrangement of vehicles and the mixing state for various types of vehicles are given by using the Monte Carlo method. The value of vibration level is obtained at a regular interval by the level summation of unit patterns corresponding to vehicles. The validity of this simulation is examined by comparison with measured values.
