高速铁路以其列车行驶速度快、安全舒适、相比其它交通方式,具有较好的节能减排比较优势,但同时也带来一系列环境问题,其中以噪声影响最大。通过从背景噪声、传播距离、源强三个方面分析铁路沿线声环境质量影响因素,提出改善铁路声环境质量的对策和建议。 Compared with other modes of transportation, high-speed railways have the advantages of comparative advantage of energy saving and emission reduction, but also bring a series of environmental problems, of which the noise is the most influential. By analyzing the influencing factors of the acoustic environment along the railway from three aspects: the background noise, the propagation distance and the source strength, the countermeasures and suggestions for improving the railway acoustic environment quality are put forward.
