| 摘 要： | 排楼隧道洞口段处在V级围岩中．围岩自稳能力差，对隧道衬砌结构带来不利的影响。本文采用荷载结构法对V级围岩衬砌结构进行了静力计算，得出初期支护和二次衬砌的最大轴力、最大弯矩，以此来评价衬砌结构的稳定性。

| Abstract: | Pai Lou tunnel entrance section is in the Five grade surrounding rock, and the stability of surrounding rock is poor,which has a negative impact on the tunnel lining structure. This paper carry out a static calculation on the lining structure by load structure method, obtain the initial maximum axial force and the maximum bending moment, evaluate the stability of lining structure. |
