本文通过对能源消耗、环境污染、土地占用面积等指标分析,指出城市轨道交通在实现城市交通可持续发展对策中是具有相当重要的地位的,值得大力发展。同时,较详细的分析城市轨道交通系统形成的噪声原因,并从降低噪声源的激振强度、切断噪声的传播途径和在传播途径上削弱噪声等方面提出了防护措施。
Based on the analysis of such indicators as energy consumption, environmental pollution and land occupied area, this paper points out that urban rail transit plays a very important role in the strategy of sustainable urban transport development and deserves to be developed. At the same time, it analyzes the causes of noise formed in urban rail transit system in detail, and puts forward some countermeasures to reduce the excitation intensity of noise source, cut off the transmission route of noise and weaken the noise in the transmission route.
