| 摘 要： | 木西岙隧道的整体式双跨连拱特殊结构以及其复杂的地形地质条件,对洞室稳定性提出了更高的要求.在充分研究工程区内地质特征的条件下,采用有限单元法对木西岙连拱隧道开挖和支护两种状态下的围岩稳定性进行分析.分析结果表明采用的村砌结构能够有效减小围岩变形,控制围岩应力,对围岩稳定性起到了很好的加固效果.

| Abstract: | Muxiao tunnel is the whole type double arch special structure,and there is complex topographic and geologic conditions are complex,The stability of excavation and supporting for cave surrounding rock is analyzed adopt finite element under the sistuation,and the geological characteristics of engineering area is also to limit well analyzed.The analytical result shows that the lining can effectively reduce the deformationl surrounding rock,to limit the stress of surrounding rock,which shows the reinforcement effect of the lining is desired. |
