摘　　要：在总结国内外铁路环境振动预测方法和评价标准的基础上,借鉴美国联邦铁路管理局(FRA)高速铁路环境振动评价方法,对曼谷新机场铁路连接线(高架轨道)引起的沿线环境振动进行初步评价,进一步采用有限元软件ANSYS分别建立车辆-轨道-桥梁耦合系统、桥梁-大地-建筑物耦合系统分析模型,运用瞬态动力学方法对该连接线引起的环境振动进行详细评价,为连接线的减振设计提供依据。On the base of the summary of prediction methods and assessment standards of vibration in railway environment in both domestic and abroad railroads, a preliminary assessment of vibration in the environment of Bangkok airport rail link （elevated railroad） was carried out. The assessment method of noise and vibration impact for high-speed ground transportation presented by U.S. Department of Transportation Federal Railroad Administration （FRA） was employed. Furthermore, models for finite element analysis for the vehicle-track-bridge coupling system and the bridge-ground-building coupling system were developed with ANSYS code. Comprehensive assessments of environmental vibration caused by the rail link were performed by means of transient dynamic theory. And the results of the assessment may be taken as a base for design of vibration reduction of the rail link. It is expected that this paper may be used as a reference for environment vibration prediction and assessment of domestic railroads.
