弹簧隔振层在民用工程整体隔振中的减振分析

Analysis of Spring Vibration Isolation Layer of a Residential Engineering

某民用建筑紧邻运营地铁线路,为减轻地铁经过时地铁振动对该建筑的影响,通过有限元数值模型计算,确定采用弹簧隔振器进行整体隔振。结合工程实测数据,详细分析弹簧隔振层在地铁通过时的减振情况。实测结果表明,弹簧隔振器能有效减小地铁振动的传递,达到了预期减振效果。

A residential building is next to operating subway line. In order to reduce the effect of subway vibration on the building,the spring vibration isolation layer is adopted by finite element calculation. Combined with engineering test data,the analysis of spring vibration isolation layer＇s effect is introduced. The monitoring results show that the effect of spring vibration isolator is good.
