隧道的初次衬砌与围岩共同作用构成了隧道的初期支护结构,荷载-结构法并不能很好的反应初次衬砌的受力情况,本文利用地层结构法对Ⅴ级围岩隧道的初次衬砌进行受力分析,模拟隧道施工过程中围岩的受力变化。
The initial lining of the tunnel and the surrounding rock make up the initial supporting structure of the tunnel. The load-structure method does not reflect the initial lining force well. In this paper, the primary lining of V grade surrounding rock tunnel Stress analysis to simulate the force change of surrounding rock during tunnel construction.
