| 摘 要： | 隧道开挖过程中，确定设计参数的合理性，以及确定所选用的施工方法能否保证隧道围岩的稳定具有重要意义。以渝湘高速公路白马隧道为依托，用有限元计算软件ANSYS对隧道开挖力学行为进行数值模拟，分析开挖后隧道的位移场、应力场，判断隧道的开挖和支护方式是否合适。模拟结果可以为隧道施工过程中支护方式和时间的选取提供合理依据。

| Abstract: | It＇ s important to determinate whether the tunnel design parameters was rationality,and whether the stability of wall-rock of road tunnel in the condition of the chosen construction method was guaranteed.Aiming at Baima Tunnel of Yuxiang Highway in chongqing, mechanical behavior of the tunnel excavation was numerical stimulated by finite element calculation software ANSYS,displacement field and stress field after the excavation was analyzed to estimate whether the tunnel excavation and supporting pattern was appropriate.Justifiable bases was provided for the supporting pattern and time choosing during tunnel construction process. |
