摘    要:根据现场实测数据,对某地铁2号线沿线典型区段地铁引起的临近建筑物振动实况和振动特性及其传播规律等进行了分析研究。结果表明:地铁诱发的沿线建筑物的振动以竖向为主,且楼层竖向振动基本表现为整体振动;在框架结构中,振动信号主要是沿柱子向上部楼层传播;楼层振动主要表现为低频的楼板振动,楼层间信号的放大主要集中在20 Hz以下的低频信号。此外,本文还给出建筑物振动实测资料的评价分析,为评估地铁运营诱发的环境振动与城市规划设计提供参考。

关 键 词:地下铁道  振动实测  整体振动  楼板振动  环境振动

Abstract:The realities,mechanism and propagation of the adjacent buildings vibration induced by the No.2 Route of a Subway were studied by in situ experimental method.The analysis results show that adjacent buildings vibration induced by urban subway transit mainly expresses the vertical vibration and the solid vibration of the buildings,that the vibration of frame structures is mainly propagated to upper floors by posts,and that floors' vibration is mainly expressed floor slab vibration,and the amplified vibration between floors mainly concentrate to the low band below 20 Hz.More over,the evaluation of the observed dataset is provided,which is helpful for evaluation of environmental vibration induced by urban subway transit and city planning and designing.
Keywords:metro  vibration measurement  solid vibration  floor slab vibration  environmental vibration
