摘　　要：大城市中心老旧城区地铁穿行地块,地铁振动及辐射噪声对周边人群的影响程度较大。研究者需对地铁振噪的成因特性进行分析,同时考虑建筑位置空间、结构围护形式等多种建筑因素与振噪的影响关系,多阶段、多位置、多工况进行现场测试,对各阶段测试结果推导,使减隔振设计方案的多态判定有效落地,促进弹簧支座隔振、减振垫隔振、浮筑板隔振等组合减隔振设计能在同一项目中融合实施。In order to mitigate the impact of vibration and radiation noise caused by subway underrunning,the causes of subway noise should be analyzed,and many related factors such as building location space and structural enclosure form should be considered.Through multi-stage,multi-position and multi-condition field test,the multi state judgment scheme of vibration reduction and isolation design of underpass subway in central city is proposed.
