摘要：
The pressure variations on train surfaces and noise barriers induced by a model train passing barriers of 0.125 and 0.25 m are studied using a 1/20 moving model. Pressure-time history curves on train surfaces and noise barriers are presented and compared with those of BS EN 2005. The influences of train speed, noise-barrier height, and crossing speed of trains are analyzed with their respective pressure distributions. The results indicate that the pressure amplitudes on train surfaces and noise barriers increase when the train speed and the height of the noise barrier increases, and the pressure amplitudes on the same noise barriers decrease significantly when the heights of the pressure taps increase.
