城市轨道交通环境影响评价中地下线路振动源强取值存在的问题与建议

The Suggestions and the Problems of the Vibration Source Intensity Data of the Underground Line in the Environmental Impact Assessment of the Urban Rail Transit

本文依据《环境影响评价技术导则城市轨道交通》(HJ453—2008)中对地铁列车振动源强的定义,总结并分析了目前城市轨道交通环境影响评价中,地下线路振动源强取值的三类方法:标准规定法、引用资料法、现场类比监测法的优缺点,在此基础上提出下阶段应进一步规范我国城市轨道交通环境影响评价中的振动源强取值方法,加强开展振动源强的系统研究,推进城市轨道交通运营期后评价工作,建立我国城市轨道交通环境影响评价振动源强基础数据库等工作内容。

According to the definition of the metro trainvibration source intensity in＂Technical Guidelines for Environment Impact Assessment of Urban Rail Transit＂ （HJ456--2008）, this paper summarizes and analysis advantages and disadvantages of three methods of the vibration source intensity data of the underground line in the current environmental impact assessments of the urban rail transit, which are standard regulating method, information referring method and field monitoring method. Giving on the basis that it should further standard the method of the vibration source intensity data in the current environmental impact assessments of the urban rail transit, and by enhancing the system research on the vibration source intensity, promote the work after the operation period of the urban rail transit, establish the basic database of the vibration source intensity in the environmental impact assessment of the urban rail transit in China.
