摘要
城市轨道交通引起的环境振动与噪声问题日益严重,越来越受到人们的重视。综述振动传播规律和常用减振降噪措施,总结当前研究存在的问题并提出相关建议。地铁诱发的地面振动存在一个振动放大区和一个主要响应频带,对建筑物的影响主要是低频振动且以竖向振动为主。从源头采取减振措施是最直接最有效的方法,主要是在车辆和钢轨两方面采取措施。目前研究最多的是从振动传播途径采取措施,包括各种扣件减振、道床和轨道减振、隧道结构减振以及各种隔振技术。对于特殊的建筑和仪器,可以采取受振对象保护措施,包括设置隔振基础、阻尼器、隔振基座和减隔振元件等。只有运用多种减振措施,才能起到综合减振的目的,从而减轻振动对环境的影响。
Environmental vibration and noise induced by urban rail transit are becoming more and more serious problems. In this paper, the rules of vibration propagation and the commonly used measures for vibration attenuation and noise reduction are reviewed. Some problems in the current research are summarized and the corresponding suggestions are put forward. There is a vibration amplifying zone and a main response frequency band of ground vibration induced by subway. The building is mainly influenced by vertical low frequency vibration. Using the vibration reduction measures for the vibration source in the aspects of vehicle and rail is the most direct and effective way. Measures of vibration reduction for the vibration transmission path are mostly studied at present, including all kinds of fasteners, damping tracks, vibration reduction of tunnel structures and various isolation techniques. For special buildings and instruments, some protection measures are usually taken, including the installation of vibration isolation foundation, dampers, vibration isolation base,vibration reduction components and so on. Only by using various vibration reduction measures, can the purpose of comprehensive vibration reduction be reached, so as to reduce the impact of vibration on the environment.
