摘要
美国联邦公共交通管理局(FTA)在FTA—VA—90—1003—2006《Transit Noise And Vibration ImpactAssessment》中提出的地铁环境振动预测方法在美国使用广泛。介绍了该预测方法的基本思想,建立了预测模型,基于北京地铁大量环境振动实际测试数据,对该方法在我国城市轨道交通环境振动预测中的可用性进行了系统分析。研究结果表明:该方法在研究思路上对北京地铁环境振动预测方法具有良好的借鉴和指导作用,但其中各重要环节和具体修正量则需依据实际情况和实测结果加以重新界定。
The prediction method on metro-induced environment vibration suggested in ＂Transit Noise And Vibration Import Assessment＂ （ FTA VA--90--1003 2006） from the Department of Public Security in USA has been widely used in America. The applicability of this method in Chinese urban rail transit environment is roundly analyzed based on the test data in Beijing metro. The result indicates that the method has a good function as both reference and indication from the researching viewpoint, especially for the test of metro-induced environment vibration in Beijing. But some important steps and corrections shall be redefined in accordance with the specific circumstances.
