Abstract Research purposes:The railway station which is under the viaduct has some advantages, such as, the land used is less, the path-line is very convenient, the function composition is compact. But because this type of railway station is located under the viaduct, so the vibration and noise which caused by the train operation have bring a few of negative affection to the physical and psychological of passengers. Therefore it is necessary to research and use some measures how to isolate the vibration and reduce the noise and control it within an allowable range, to provide a higher standard and comfortable indoor environment for passengers.
Research conclusions:(1)The Station-building uses the structure of ”separation of bridge and building". The structure in the transmission of vibration and noise valid can weaken their station indoor acoustic environment. (2) The vibration and noise are based on the low-frequency in station. The feature selection should be based on its frequency appropriate materials and construction practices. (3)Decoration materials both inside and outside in the station should use lightweight materials and elastic structure. (4) Improving the indoor environment can enhance the applicability of this station type.(5)This research results can provide reference to the similar projects.
