摘　　要：随着城市轨道交通的大量新建以及客运专线、城际铁路的快速发展,由此引起的线路环境振动与噪声问题日益突出,已成为城市建设与发展中人们关注的焦点之一。在国内外学者研究的基础上,作为应用实例,对某机场城市轨道交通连接线引起的环境振动进行了预测和评价,提出了适合我国城市轨道交通的环境振动预测和评价方法。Informative abstract With the rapid development of urban mass transit（UMT）, the dedicated passenger line and intercity railways, the impact of vibration and noise induced by railway transportation is becoming a prominent point at issue. Many researches have shown that the vibration caused by the transport system does not make structural damage to railway construction, but will affect people＇s work and rest when the vibration reaches to a certain level. Besides, the vibration will interfere with the proper working of some precision instruments. Therefore, the vibration induced by the URT shall be predicted and evaluated, some effective measures be adopted when the vibration excesses the normal standards. Methodologies of predicting and assessing the vibration and noise of UMT are introduced in this paper based on the previous studies at home and abroad, including selection, general assessment and detailed analysis. Taking the rail link of an airport as a practical example, the prediction and assessment of vibration and noise are presented, some key points in the detailed analysis are stressed.
