| 摘 要： | 通过在北京地铁5号线高架桥梯形轨枕轨道试验段上进行的现场噪声测试,对比分析列车通过梯形轨枕轨道和簿通板式轨道时桥梁附近的噪声,研究梯形轨枕轨道的噪声频谱特性及随列车速度变化的规律.测试结果表明:梯形轨枕轨道的降噪能力明显优于普通板式轨道,从时域看,噪卢随符列车速度的增加而增加.但足梯形轨枕轨道的噪声值比普通板式轨道低;...

| Abstract: | Field measurement was conducted at the test section of the ladder sleeper track on the elevated bridge of Beijing Metro Line 5.The site noise near the bridge was measured and analyzed when the train running on the ladder sleeper track and the common slab track.The spectral characteristics of the noise and the variation laws of noise with respect to train speed were studied.The test results indicate that the ladder sleeper track has better noise-reduction performance than the common slab track.In the time do... |
