高速铁路环境振动分析参数选取对评价结果的影响规律研究

Study on the Influence of the Selection of Parameters on the Evaluation Results of High-speed Railway Environmental Vibration Data Analysis

目前我国与高速铁路运行引起的环境振动相关的标准体系尚需完善,可供参考的国际标准制定时间较早,国内外对铁路和城市轨道交通环境振动的标准存在较多差异。结合实测数据研究了计权曲线和时间计权常数的选取对评价结果的影响规律,指出量化的差异及产生原因,成果可以为日后制修订我国高速铁路环境振动相关标准提供参考。

The China's standard system related to environmental vibration caused by high-speed railway still needs to be improved at present,and the national standard for reference is formulated earlier.Therefore,there are more differences between domestic and international standards for railroads and urban rail transit environmental vibration.This paper uses the actual measured data to study the influence of the indicators on the evaluation results of the vibration,including the weighting curves and time weighting constants.The quantitative differences and the reasons are pointed out,which can be used as a reference for the future formulation and revision of the national high-speed railway environmental vibration standards.
