京沪高速铁路噪声源控制技术的应用及其降噪效果

The Application of the Control Technology of the Noise Source and the Effect of Its Noise Reduction of Beijing-Shanghai High-speed Railway

本文总结分析了京沪高速铁路噪声源控制技术及其应用效果。经现场监测得到京沪高速铁路环境噪声影响状况。结果表明,京沪高速铁路试运营阶段,在平均车流量及运行速度为300 km/h且设置声屏障条件下,铁路边界噪声和位于4类区的敏感点噪声影响均可达到《铁路边界噪声限值》(GB12525—90)和《声环境质量标准》(GB3096—2008)中4类标准要求。

This paper summarizes and analyzes the the details of the control technology of the noise source of Beijing-Shanghai high-speed railway and the effects of its application, reaches the infection situation of the environmental noise of Beijing-Shanghai high-speed railway by field monitoring. The results show that in the stage or trial run of Beijing-Shanghai high-speed railway, under the condition of the normal traffic and the speed is 300 km/h and being set the noise barrier, both of the railway boundary noise and the noise on the sensitive point located in the Ⅳ class region could reach the requirements of the IV class standard in Railway Boundary Noise Limit （GB12525-90） and Acoustic Environment Quality Standard （GB3096-2008）.
