摘要: A solution procedure is presented to compute free field vibrations induced by train or road traffic, the excitation being either deterministic stochastic. The full interaction between vehicle, track and soil accounted for, using a substructure approach that takes advantage of fact properties do not change along longitudinal direction. time-frequency proposed characterize radiated in soil. examples show importance guided waves for understanding dynamic behavior road.
