Study on Evaluation Index of Environmental Vibration Induced by Urban Transit
Abstract Index to evaluate environmental vibration induced by urban rail transit are VLzmax and VLmax. Confused calculating methods of evaluation index have affected plan and design of subway line. Influence of overlapping coefficient and frequency weighting curve on VLzmax is researched in this paper. The study found that when the overlapping coefficient is 3/4, the result of VLzmax is stable basically. Frequency weighting curve in ISO 2631-1:1997 considering the effect of rail transit vibration on human health, comfort and perception, which is recommended for the amendments on the GB10070-88 Standard. Calculating methods of linear averaging, peak hold have significant influence on the VLmax result, which could affect the evaluating result. In order to ensure the reliability of evaluation results, peak hold method should be adopted as the calculating method.
