基于城市现代有轨电车建设的环境影响分析--以沈阳有轨电车建设项目为例

摘要

As the development of the cities and grow th of its population and the number of cars ,Public trans‐port need to upgrade ,Rail transit has become the direction of development of urban public transport system . ShengYang modern tram is the first project in china ,Construction of the environmental impact is mainly me‐chanical noise ,dust and solid waste ,Operation of environmental impact from noise .According to the predic‐tion results of typical road ,In the case of maximum operating speed of trams ,20m away from the centerline of the track ,most of the sections can satisfy the Class 2 functional area noise standards ,Because of the back‐ground noise is large so individual sections exceeded .Noise contribution value of the project is very small , Will not have a significant impact on noise-sensitive points .%指出了近年来随着城市的发展，人口和汽车数量不断增多，公共交通体系急需升级，轨道交通成为城市公交系统发展方向之一。以沈阳有轨电车项目为例进行了分析，根据典型路段预测了结果：在有轨电车最高运行时速情况下，距轨道中心线20m处，大部分路段均能满足2类功能区噪声标准要求，个别路段超标原因是本底噪声较大。有轨电车项目对噪声增加的贡献值较小，不会对噪声敏感点产生较大影响。
