| 摘 要： | 本文根据现场实测数据,对某地铁交通1号线沿线典型区段引起的环境振动实况和振动特性及传播规律等进行了分析研究。结果表明,地面振动Z振级主要由测点到轨道中心的水平距离决定,并且在离开地铁隧道中心线一定距离范围内,地面振动Z振级存在振动放大区。此外,本文还根据实测资料和现有研究成果提出了该地铁1号线引起环境振动Z振级的统计回归公式。该式从数学表达式的角度反映了振动信号的放大效应,可为预测或估计地铁运营诱发的环境振动提供参考。

| Abstract: | The reality,the mechanism and the propagation of the environmental vibration induced by the No.1 Route of a subway are studied by in situ experimental method.The analysis results suggest that Z direction environment vibration transportation is controlled by the level distance from tunnel central line and amplified at certain distance away from tunnel centre.Based on the observed dataset and existing research results a statistic regression formula is presented to predict the environmental vibration induced by the No.1 Route of this subway.It reflects the existence of environment vibration amplification by means of mathematical expression and will provide a reference for predicting environmental vibration. |

| Keywords: | metro environmental vibration vibration measurement degree of Z direction vibration vibration amplification |
