Abstract

An average increment of Shinkansen-induced ground vibration has already been estimated for the entire Shinkansen network using previous measurement results; however, the degree of train-speed dependency varies considerably along the same line. Therefore, an evaluation method for the train-speed dependency at each point along a given line is required to estimate the cost and extent of any necessary countermeasures. This paper starts with a discussion of Shinkansen-induced ground vibration characteristics. Then we propose an evaluation method for the train-speed dependency of train-induced vibration using simple models of the ground dynamic characteristics, excitation force, and the effect of periodic axle load.
