摘要
在对城市轨道交通的噪声源特点进行分析的基础上,介绍噪声预测方法,并与国外的成熟方法进行对比分析;重点介绍把城市轨道交通噪声作为一个线声源、噪声源分解为轮轨噪声和牵引噪声等分别进行预测的方法,并给出了详细的计算步骤。以此方法对昌九城际轨道交通的噪声水平进行预测,得到沿线敏感点在昌九城际轨道交通影响下的环境噪声级。
The characteristics of the noise source of high-speed rail transport are paper. Some methods for railway noise prediction at home and abroad are introduced and noise prediction method, that the noise of high-speed railway is regarded as a line noise analyzed in this compared. The source, and divided into propulsion noise and wheel-rail noise, for urban railway transport is introduced in detail. With this method, the noise level of Nanchang-Jiujiang intercity rail transport is predicted. The environmental noise levels of some noise-sensitive areas along this railway are determined.
