摘要：

以共和新路地铁-双层高架轨道交通系统为背景，研究了城市立体交通体系所引起的振动和环境噪声问题.通过对地下车站、地面周边和双层高架等不同区域的测量与频谱分析，获得1/3倍频曲线和等效声压级，分析了不同构造形式的轨道交通所诱发的辐射噪声及其分布规律，为城市立体轨道交通体系的建设、环境评价和噪声控制提供了有益的参考.

关键词: 噪声理论；快速傅里叶变换；数据分析；环境评价

Abstract:

This study takes the multi-layer mass transit of Gonghexin Road, Shanghai, as an example, which has a subway line with a doubledecker elevated track. Vibration and environmental noise caused by the urban mass transit was investigated. Noise measurement was done in the subway, on the ground and on the double-decker elevated track. Based on the date and their spectral decomposition, curves of one third octave characteristics and equivalent sound pressure levels were obtained. Further analyses were carried out on the rules of normal noise for different mass transits. The results are useful for the urban development, environmental evaluation and noise control.

Key words: noise theory; fast Fourier transform (FFT); data analysis; environmental evaluation
