［摘要］中国目前与地铁运行引起的建筑物室内环境振动相关的规范和标准约有十余种，国外也有多种针对人体全身振动的相关规范。各规范和标准针对城市轨道交通引起的环境振动提出了严格和详细的要求，包括环境振动的测量方法、评价量的计算方法和适用条件及城市各类区域的振级评价量限值。但各规范和标准在上述各方面存在差异，给工程应用带来一定程度的混乱。首先梳理了不同规范和标准中测量方法、评价量和限值的异同，再通过MATLAB程序试算道路交通及城市轨道交通引起的建筑物内楼板中央的垂向振动加速度时程，比较不同规范和标准对环境振动要求的严格程度和适用范围，最后提出一些针对现有规范和标准的改进建议。

Abstract:There are a dozen of specifications and standards related to the subway-induced environmental vibration currently in China. And there are also several specifications about human body vibration issued by other countries or international organizations. All those specifications and standards regulate strict and detailed requirements to the urban rail transit-induced environmental vibrations, including measurement method of vibrations, the calculation methods of vibration assessment value and applicable conditions, and vibration assessment value limit of various type of urban area. But the differences in the above aspects between these specifications and standards bring a certain degree of chaos in the enginering practice. Firstly the similarities and differences about measurement method, evaluation and allowable limits of these specifications and standards were summarized. Then, the MATLAB program was used to calculate the vertical vibration acceleration time history at the center of the indoor slab induced by road traffic and urban rail transit respectively to compare the degree of rigor and the scope of application among these specifications and standards. At last, some recommendations for the improvement of existing specifications and standards were suggested.
