摘要
为了研究地铁振动对周围场地的影响,文章基于苏州既有轨道2号线的实测数据分析,通过对实测数据的预处理及响应分析,得出实测地铁振动对于周围场地的影响。利用ANSYS有限元分析软件对地铁振动进行二维建模,选取适当的模型大小、单元网格尺寸、时间步长、阻尼系数以及边界条件,结合国内外学者的研究成果对列车竖向荷载进行确定,通过软件分析得出模拟和实测之间的对比时程图和频谱图,最终给出地铁振动对周围场地影响的一些意见。
In order to study the influence of subway vibration on the surrounding area based on the measurements of the Suzhou existing rail line 2 analysis, through pretreatment and the response analysis of the measured data, it is concluded that the measured subway vibration effects on surrounding site. Using ANSYS finite element analysis software to two dimensional modeling of the subway vibration, select the appropriate model unit size, mesh size, time step, damping coefficient and boundary conditions, combined with the research results of domestic and foreign scholars on the train vertical load simulation is determined by software analysis and comparison between the measured time history diagram and the frequency spectrum diagram, finally it shows some opinions of the subway vibration influence on the surrounding space.
