针对某隧道浅埋段围岩压力过大问题,采用数值模拟对注浆初支后的隧道浅埋段围岩进行计算。计算结果表明,隧道围岩浅埋段在进行了注浆加固与初支之后变形量得到了有效控制,处于相对稳定状态。
Aiming at the over-pressure of surrounding rock in the shallow buried section of a tunnel, numerical simulation is used to calculate the surrounding rock of shallow-buried section of the tunnel after the initial grouting. The calculation results show that the deformation of shallow section of surrounding rock of tunnel after grouting reinforcement and initial branch are effectively controlled and relatively stable.
