| 摘 要： | 将列车荷载模拟为单一的移动荷载，考虑围岩为黏弹性成层地基，利用分层法研究了移动荷载作用下围岩的动力响应，得到了围岩在动力荷载下的受影响范围，从而可评价列车荷载对下穿公路隧道稳定性的影响程度。最后将理论分析结果与现场量测结果（主要是上方列车荷载通过时量测下方公路隧道的振动响应）进行对比分析，二者吻合较好。

| Abstract: | By considering train load as single linear moving load and rock mass as viscoelastic layered ground, the paper analyzes the dynamical response of the rock below the moving train with the Multi－Layer method. The affecting range of the moving load is obtained , thus the affecting extent of the moving train load on the stability of the underlying highway tunnel can be evaluated. The comparison of theoretical analysis with site monitoring results(mainly about the vibration response of the tunnel) shows that they accord with each other. |
