随着城市轨道交通的快速发展和人们生活质量的提高，地铁列车运行引发的振动噪声问题引起了广泛关注，并且成为地铁开通运营后面临的主要问题之一。针对南京地铁1号线珠江路站旁地铁大厦内噪声较大的问题，在线路上采取了钢轨低接头打磨和换铺嵌套型减振扣件等振动噪声整治措施。为了评估整治效果，对措施实施前后隧道壁振动、室内振动及噪声进行了对比测试。测试结果表明，整治后珠江路站及周边建筑的振动噪声水平大幅降低，整治效果明显。

With the rapid development of urban rail transit and the desired improvement in the quality of people’s lives, environmental vibration and noise problems caused by urban rail transit have attracted increasing attention. This is one of the main problems faced by a subway after it begins operation. In order to solve the indoor noise problem in the subway building next to Zhujianglu Station of Nanjing Metro Line 1, remediation measures were taken in subway lines, including rail grinding and the replacement of vibration reduction nested fasteners. To evaluate the effect of this remediation, comparative tests were conducted on the tunnel wall vibration, indoor vibration, and noise before and after the implementation of the measures. The test results show that the vibration and noise levels within Zhujianglu Station and surrounding buildings are greatly reduced after remediation, and the remediation effect is obvious.
