摘　　要：研究目的:线正下桥式车站具有功能布局紧凑,旅客流线便捷,节约用地及投资的优势。但由于站房位于铁路线路正下方,列车产生的振动和噪声对站房使用及旅客生理、心理感受产生很大的不利影响,所以有必要对桥式车站的隔振降噪技术措施进行深入的研究,将振动、噪声控制在容许范围内,为乘客提供高标准、高舒适度的候乘环境。研究结论:(1)站房采用"桥梁、建筑分离"的结构方式可以在振动和噪声的传播途径上有效减弱其对站房室内声环境的影响;(2)车站的振动和噪声频率均以中低频为主,应根据其频率特征选择恰当的材料和构造做法;(3)站房内外装修装饰材料宜选用轻质材料及弹性构造;(4)室内环境的改善可以增强桥式车站的适用性;(5)本文研究成果可供类似工程借鉴。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 simllar projects.
