关于《环境影响评价技术导则:城市轨道交通》中若干问题的探讨

Discussion of Some Questions In Technical Guidelines for Environment Impact Assessment of Urban Rail Transit

随着城市轨道交通的发展,车辆运行时所引起的环境振动问题日益引起人们的关注。通过研究国内外由轨道交通引起环境振动的评价方法,及所做的一些现场实测,对《环境影响评价技术导则:城市轨道交通》(征求意见稿)中的若干环境振动评价问题进行了讨论,包括监测点的布置位置、高架轨道的振动评价、本底振动的评价、预测公式中的修正项以及不同建筑物类型的划分等。

As the development of urban rail transit, more and more attention has been paid on the environmental vibrations caused by the vehicles＇ running. Through the study of domestic and overseas environmental vibrations impact assessment of urban rail transit and a series of measurements, a discussion of some questions about the assessment of environmental vibrations in Technical Guidelines jot Environment Impact Assessment of Urban Rail Transit（Consultative paper） is given in this paper, including the measurement locations , the vibration assessment of the elevated railway, the evaluation of the backgound vibrations, the adjustments to predictor formula and the division of different building types.
