摘要

城市交通拥堵问题日益成为影响城市运转的重大问题,高架轨道交通是解决该问题的重要方式。高架轨道交通的运行过程中产生的噪声影响沿线居民的正常工作和休息,降低高架轨道交通噪声污染成为建造高架轨道交通必须解决的问题。建立一套适用于高架轨道交通噪声辐射的模型,有助于在建造轨道交通线之前合理的预估由于轨道交通造成的噪声辐射影响及传播特性,能使轨道线路设计初期就预先获知可能产生的噪声影响,从而改进设计方案。将列车视作一个线声源,各处声功率强度相等,采用单极子和偶极子传播模型拟合轻轨列车的通过噪声,建立了一种较为简单实用的预测模型,并通过高架轨道交通线附近的测量数据,分析了不同测点情形下模型的适用性,为今后预测高架轨道交通线的噪声辐射提供了参考。

Abstract

The traffic jams in cities are an important problem affecting the city's operation. Modern urban mass transit is an effective solution to alleviate the traffic jams, one of which is the elevated viaduct rail transit. Elevated viaduct brings along with the noise pollution, which seriously disturbs people’s lives in the community nearby and should be controlled. The establishment of a model can predict the traffic noise radiation and evaluate its impact to the places along the elevated viaduct. It helps to optimize the design of the elevated viaduct and lower the noise disturb. The train noise profile is modeled by assuming the train noise to be a line with constant power per unit length. Both monopole and dipole directivity are employed to describe the spread of train noise. The experiment was done to illustrate the validity of models. These two models are suitable to the different cases. This work provides a reference for predicting the train noise radiation on the elevated viaducts.
