| 摘 要： | 通过对现场铁路列车辐射噪声测量和理论分析计算，结合影响铁路声屏障降噪效果主要因素，得出如下结论：当列车运行速度低于250km／h时，对铁路沿线1～2层噪声敏感点建筑，采用防撞墙既有效又经济；声屏障相对越高、距轨道中心线越近，降噪效果越好。

| Abstract: | Through field measuring and theoretic calculation to train noise, combined with main influential factors to noise mitigation effect of railway sound barrier, proof wall is considered to be effective and economical to the noise sensitive building with 1 or 2 floor along railway when the train speed is lower than 250 km/h. Effect of noise barrier will be more better if the barrier is more higher and more nearer to the center of the tract. |
