城市轨道交通噪声控制技术研究

Research on noise control technology of urban rail transit

随着城市现代化的不断发展,交通拥堵越来越成为必须面对和解决的问题。目前国内30余个大中城市已建成或即将启动轨道交通项目,希冀其成为解决城市交通的重要手段。但城市轨道交通在带给城市人员出行方便的同时,高架线路及地下车站风亭、冷却塔产生的噪声问题亦越来越突出,因此通过工程技术手段控制噪声污染尤为必要。本文根据已运营轨道交通项目噪声现状情况,结合工程实践提出有效噪声防护措施。

With the development of modern cities, traffic congestion is becoming a problem to be faced and solved. At present, more than 30 large and mediumsized cities have built or are about to start rail transit projects in China, and they hope the projects to become important means to solve the city traffic problems. However, while urban rail transit brings convenience to urban people, the noise problems of overhead lines, underground station pavilions and cooling towers are becoming more and more prominent, so it is particularly necessary to control noise pollution by means of engineering technology. According to the present noise situation of the rail transit projects, effective noise protection measures are put forward according to the engineering practice.
