模型実験による山陽新幹線防音壁形状の評価

抄録

In the Sanyo Shinkansen railway line, the wayside noise along the line has been reduced by the improvement of the sound barriers. The configurations of the barriers have been arranged differently by taking account of the noise at each section along the line. Furthermore, it is necessary to make the barriers be renewed in order to maintain the facilities on a sustainable basis. In this paper, the simulations for four types of the barriers are carried out by using scale model experiments, and the results obtained by the model experiments are compared with those by the field measurement.
