Abstract: This study focuses on a street-front building in Wuhan, investigating the indoor vibration and noise characteristics of buildings subjected to multi-level transportation through field measurements. The indoor vibration and noise levels were evaluated in accordance with the standard JGJ/T 170-2009.The results indicate that among various single vibration sources, the excitation from an arriving subway has the most significant impact on indoor vibration. Under multi-source conditions, as the number of vibration sources increases, the peak acceleration of indoor vibration increases, the frequency distribution broadens, and the vibration response across all frequency bands is amplified. Both the peak vibration acceleration and the maximum sound pressure level at the center of the indoor floor slab exhibit a trend of initially decreasing and then increasing with the rise of the building floor. Indoor vibration levels are higher during off-peak periods and at night, but lower during morning and evening peak hours. Conversely, indoor noise levels are higher during morning and evening peak hours and lower during off-peak periods and at night. The vibration of the floor slabs in rooms on all floors meets the standard limit requirements; however, the indoor noise level on the fifth floor exceeds the specified limit.This research provides valuable guidance for reducing interference caused by traffic vibration and traffic noise to residents along urban multi-level transportation routes.

摘要： 摘要：本文以武汉市某临街建筑物为研究对象，通过现场实测对多重立体交通临近建筑物室内振动与噪声特性进行了研究，结合标准JGJ/T 170-2009对建筑物室内振动和噪声进行评价。研究结果表明：在各种单一振源激励中，地铁进站激励对室内振动影响最大，多振源工况下，随着振源数目的增加，振动峰值加速度增大，建筑结构振动在频域上的分布范围扩宽，各频段的振动响应均增大；室内楼板中央位置的振动峰值加速度和最大声压级均随建筑楼层的增加呈先减小后增大趋势；室内振动在平峰期间及夜间较大，而在早晚高峰期间较小；室内噪声水平在早晚高峰期间较大，平峰期间及夜间较低；各楼层房间楼板振动均满足限值要求，而五楼室内噪声水平超出限值。该研究对解决城市多重立体交通给沿线居民带来的振动和噪声问题具有一定的指导意义。
