以北京地铁浮置板轨道为研究背景,建立隧道—土体—建筑物二维有限元模型,考虑不同工况下该浮置板轨道系统的振动对邻近建筑物的影响,并对建筑物振级随参数变化的规律进行了分析,以期为研究地铁附近建筑物的减振提供指导。
Taking the Beijing Metro floating slab track as a research background, a two-dimensional finite element model of tunnel-soil-building is established. The influence of the vibration of the slab track system on the adjacent buildings under different operating conditions is considered. Level with the parameters of the law was analyzed in order to provide guidance for the study of vibration damping near the subway.
