摘　　要：根据目前我国轨道交通客运系统分类,分析了不同类型轨道交通主要设计标准差异,结合大量现场测试案例及相关标准规范,分类给出了高速铁路、城际铁路、市域铁路、城市轨道交通动车组运行噪声源强值,并分析得到:同等动车组运行速度及测点位置处,城际铁路动车组运行噪声源强高于高速铁路3.5 d B(A);城市轨道交通地铁系统动车组运行噪声源强值高于城际铁路6~7 d B(A),高于跨座式单轨系统5~7 d B(A),高于低中速磁浮系统4~11 d B(A)。Based on the current classification of passenger transport system of rail transit in China,this paper analyzes the differences between major design standards of rail transit of different types,and combined with a large number of field test cases and relevant standards,identifies the source intensity of the electrical multiple units（ EMUs） of high-speed railways,interurban railways,city region railways and urban rail transits as follows： at the same operation speed and measuring position,the source intensity of interurban railway EMUs is 3. 5 d B（ A） higher than high-speed railways,and the source intensity of metro system EMUs is 6-7 d B（ A） higher than interurban railways. Moreover,the source intensity of metro system EMUs is 5-7 d B（ A） higher than cross-saddle single-tracks,and 4-11 d B（ A）higher than medium and low speed maglev systems.
