| 中文摘要: |
| 重庆作为典型山地城市,独特的城市空间形态产生了轻轨系统与其沿线建筑特有的空间关系,使得轻轨噪声的影响变得更为复杂。本文以重庆市轻轨建设现状与空间形态特征的分析研究为基础,选取了轻轨2、3号线沿线的三处典型地段进行声环境测试,测试结果表明,轻轨通过时噪声会增加10-25 dB(A),而山地城市多轻轨线路多弯道,列车通过400m以下小半径弯道时噪声平均比直行状态高2-3 dB(A),同时轻轨在进出隧道时,其噪声的持续影响时间平均增加10-12s。 |
| 英文摘要: |
| As a typical mountainous city, Chongqing’s undulating terrain creates unique spatial relationships between light rail and its surrounding areas, resulting in more complicated effects of light rail. In this paper, three typical areas close to light rail with different features were selected, on the basis of the analysis of the relevant spatial patterns in Chongqing. According to data measurement, the noise could increase about 10-25dB(A) when light rail passed by. And there are many curves in mountainous city. When light rail is under 400m radius, its noise can increase about 2-3dB(A); When light rail entered the tunnel, it made the average noise duration about 10-12s longer. |
