摘　　要：对地铁高架车站站厅层低频结构噪声的量值、频谱特性及影响因素进行了调研,对站厅层噪声限值标准进行了分析,提出以列车通过时段等效A声级作为控制指标的两级限值。分别从车站结构、轨道减振及吸声隔声等方面,对新建线及既有线提出了站厅层噪声的控制技术措施建议。Through investigation into the values,spectrum characteristics and influencing factors of the low frequency structural noise on elevated station hall floor,the noise limitation standards for station hall floor are analyzed,the equivalent A sound level during train passing is taken as the control in原dex for a two level limitation value.Control measures for the noise control on station hall floor for both the new and existing lines are proposed from aspects of station structure,vibra原tion damping track and sound absorption and so on.
