摘要:
针对温州市域快速轨道交通项目，分析了列车运行噪声和振动对环境影响的特点，提出了减振降噪的综合措施。从车辆选型、优化高架段桥梁梁型、选用高阻尼减振支座、采取轨道减振降噪措施等方面进行源强控制；通过设置声屏障进行噪声传播控制；优化调整轨道周边地块规划，提高周边建筑隔音性能来进一步降低噪声振动的环境影响。实际应用效果表明，上述减振降噪综合措施切实有效。
Abstracts:
Taking Wenzhou urban rapid rail transit project, the impact characteristics of operational vibration and noise on the environment is analyzed, and comprehensive measures for vibration and noise reduction are proposed. Source strength is controlled by vehicle selection, elevated section bridge beam type optimization, and high damping bearing selection, track vibration and noise reduction. Transmission is controlled by setting noise barrier. The planning of surrounding plots is adjusted and optimized and sound insulation of surrounding buildings is enhanced to further reduce environmental impact caused by noise and vibration. Practical application results show that the above comprehensive measures for reducing vibration and noise are concretely effective.
