| 中文摘要: |
| 针对盾构隧道下穿城市高架对高架桥影响问题，运用FLAC3D数值分析软件模拟盾构动态施工过程对高架桥桩基的影响。数值模拟结果显示盾构施工对高架桥桩基的影响主要表现在桩体的竖向和水平位移上，对桩体水平位移的影响要大于竖向位移；对桩体水平位移影响在桩顶较大，随着桩体深度增加桩体水平位移逐渐变小。 |

| FLAC3D be used to analyze the impact of shield tunnel construction on viaduct pile foundation, according to shield tunnel construction undercrossing the urban viaduct. The numerical simulation results revealed that the impact on horizontal displacement of the pile is greater than the vertical displacement, the horizontal displacement on the top of the pile is greater, then gradually become smaller with depth increasing. |
