【摘要】：研究目的:随着中长期铁路网规划的实施,我国铁路建设快速发展,噪声问题也日益引起公众的高度关注。铁路两侧声环境功能区超标成为普遍问题,因而部分铁路项目因噪声影响尚未通过竣工环保验收。为规范、统一铁路建设项目环境影响评价和设计中噪声防治目标和措施选择,解决工程竣工环保验收中噪声治理问题,因此开展铁路噪声治理原则及措施适用条件专题技术研究是非常必要的。研究结论:(1)铁路噪声防治优先考虑对噪声源和传声途径采取工程技术措施,实施噪声主动控制,至少保证室内合理的声环境质量;(2)列车噪声源主要集中在车体2.0 m以下的轮轨区域,轨面以上高度2.05 m的声屏障能够有效屏蔽轮轨区域和车体下部区域直达声;(3)在声屏障设计时,声屏障防护范围、高度、加长量应根据铁路的源强特性,结合敏感点降噪要求、地形、地貌等工况条件采取不同的设计参数;(4)本研究结论可为铁路噪声的防治提供参考。
[Abstract]:Research objective: with the implementation of medium and long term railway network planning, railway construction in China has developed rapidly, and the noise problem has been paid more and more attention by the public. It is a common problem that the sound environment function area on both sides of the railway exceeds the standard, so some railway projects have not passed the environmental protection acceptance due to the noise effect. In order to standardize and unify the selection of targets and measures for noise prevention in environmental impact assessment and design of railway construction projects, and to solve the problem of noise control in environmental protection acceptance of completed projects, Therefore, it is very necessary to carry out special technical research on the principles and applicable conditions of railway noise control. Conclusion: 1) the railway noise prevention and control gives priority to the adoption of engineering technical measures for noise sources and sound transmission channels, and the implementation of active noise control. At least ensure a reasonable indoor sound quality) the train noise source is mainly concentrated in the wheel-rail area below 2.0 m of the car body. The noise barrier of 2.05 m above the rail surface can effectively shield the wheel-rail area and the lower part of the car body through the sound barrier 3) in the design of the sound barrier, the protection range, height and length of the sound barrier should be based on the source strength characteristics of the railway and the noise reduction requirements of the sensitive points should be combined. Different design parameters are adopted in the working conditions such as topography and geomorphology. The conclusion of this study can provide a reference for the prevention and control of railway noise.
