摘要
结合上海市高架轨道交通噪声环境影响的特点,应用类比和计算的方法,探讨了高架轨道交通噪声源强及垂向分布规律。即列车在高架轨道上以50~60km/h行驶时,高架轨道交通噪声随测点与轨道垂直方向的水平夹角的增加而呈增加趋势。但是列车上行时,在水平夹角大于16.2。和列车下行时,在水平夹角大于14.7。时列车噪声值变化甚微。
The article is associated with the character of noise environmental influence for urban track communication in Shanghai. The environmental impact assessment method was discussed through the way of analogy and calculating. And the method of the noise value for elevated track communication was confirmed, the variational law of noise perpendicularity is set up.
