运用ANSYS有限元软件,模拟弹性支承块式轨道结构模型.模型中采用DTIII2扣件,弹性支承块整体道床,荷载为实测的弹性支承块下的DTIII2扣件的轮轨力.结合穿越上海市某小区的地下轨道振动实测情况,选取不同测点进行振动响应计算.结果表明,模型中,地面测点的振动响应值同实测数据基本吻合,道床及隧道测点处的振动响应值略高于实测数据.

The elastic supporting piece of track structure model was simulated by means of ANSYS finite element software.In the model DTIII2 buckles,the elastic supporting piece of the track was used to support the elastic supporting the load of the DTIII2 buckles under the wheel/rail force.Through the combination of a residential area underground rail vibration,the site selection for different points of vibration response was calculated.The results show that in the model,the ground vibration response value is accord with the measured data results,while the track and tunnel in vibration response value of measuring point is slightly higher than the measured data.
