| 摘 要： | 文章采用ANSYS有限元分析软件对云桂铁路思林2号V级围岩浅埋偏压条件下隧道初始状态、开挖后支护两种工况下的围岩位移、应力分别进行分析和稳定性评价，结果表明：偏压隧道最不利位置出现在隧道偏向山脊一侧的拱脚处：而实施初期支护能保证围岩的稳定性，且设计的初期支护方式能够满足安全要求。

| Abstract: | This paper respectively analyzes the surrounding rock displacement and stress by using ANSYS of the finite element analysis software according to si Lin 2 Yun Gui railway for Grade V bias surrounding rock under two kinds of conditions： the initial state, suppoert after excavation. The results show that： the most unfavorable position in the tunnel is found at the ridge side of the arch; and the implementation of initial support to ensure the stability of surrounding rock, and the design of the early Support approach to meet the safety requirements. |
