| 摘 要： | 以山西省岢临高速公路某黄土隧道为工程背景,采用ANSYS有限元软件分析了台阶法开挖方式下不同围岩应力释放率对初期支护结构的受力影响。分析结果能较为合理地反映支护结构的实际受力状况,可为黄土隧道初期支护参数的合理选取提供相关参考。

| Abstract: | Combined with a loess tunnel of Kelin Highway in Shanxi Province as the engineering background, using ANSYS finite element software, this paper analyzed the influence of the different surrounding rock stress release rate on the initial support structure stress under the step-excavation method. The analysis results reasonably reflected the real stress condition of supporting structure, which provided the relevant reference for reasonable selection of loess tunnel initial support parameters. |
