摘 要: 为研究地铁振动对沿线单层砌体结构的动力影响,对北京某地铁线特定区间的单层砌体结构进行铅垂向和水平向振动加速度测试。同时,为研究不同距离处单层砌体结构的振动,对测试区街面进行铅垂向振动加速度测试。根据室内地面铅垂向计权振动加速度级,推出相同距离处街面铅垂向计权振动加速度级的修正量。由此,修正测得的不同位置街面铅垂向计权振动加速度级。最终,拟合得到地铁线不同距离处单层砌体结构室内地面铅垂向振动加速度级的分频计算公式。

Abstract:In order to analyze vibration characteristics of the single-story masonry structures nearby metro lines, vertical and horizontal acceleration on the floor of the single-story masonry structure was tested in Beijing. Furthermore, the vertical acceleration of different positions on the street near the tested masonry structure was tested as well. Through the weighted acceleration levels on the floor of the tested masonry structure, the modified values between the tested masonry structure and the tested street were obtained. Based on the modified values, the weighted acceleration levels of different positions in the street were modified. Finally, the calculation formula was derived, which can calculate the floor vibration of the single-story masonry structure in different distances with the metro line.
