| 摘 要： | 利用平面数值模拟方法,以某浅埋偏压的公路隧道施工为背景,对隧道左右洞开挖顺序进行施工数值模拟,分析开挖过程中围岩应力的变化情况,找到两种开挖方式在整个开挖过程中最容易产生破坏的施工步骤,得出浅埋偏压隧道先开挖深埋侧可避免出现较危险的施工状态这一结论,对研究类似工程的施工具有一定的指导意义。

| Abstract: | Based on a shallow-buried unsymmetrical loading tunnel,the paper simulates the process of left hole and right hole′s excavation by planar numerical simulation method in order to analyze the change of stress of surrounding rock,finds out the construction steps which are easiest to be damaged by the above two excavation modes during excavation,and draws a conclusion that excavating deep-buried side of the shallow-buried unsymmetrical loading tunnel first can avoid occurrence of dangerous construction state,in hope of providing a certain guidance for research on construction of similar projects. |
