研究隧道掌子面后方隧道拱顶、掌子面正上方和侧面围岩的爆破振动规律。
The blasting vibration rules of arch crown and upper and side surrounding rocks behind tunnel face are studied.
而隧道拱顶的下沉过程及其最终下沉量则是隧道支护设计及地层环境控制的重要基础。
Therefore, the vault crown subsiding process and its total settlement are important factors for tunnel supporting design and environment controlling.
最后，游客们鱼贯而出，进入一条广阔的拱顶隧道，这条隧道通向维也纳河，是影片中一处令人印象深刻的取景点。
Finally, visitors spill out into the vast, vaulted tunnel that channels the Vienna River and that provided a memorable setting in the film.
隧道加深一米需要1天的时间，而浇铸混凝土墙壁和拱顶需要3天多的时间。
The tunnel deepening for 1 meter takes one day. Three days more - for concrete casting of the walls and the arch.
结果表明：对于埋深较浅的隧道，如果拱顶围岩压力按均布进行计算，结果会产生较大误差。
The results show that, for relatively shallow embedded tunnel, a big error would occur if the surrounding rock pressure of the vault is regarded as uniformly distributed.
隧道边墙中部、拱肩、拱顶是比较关键的部位，应加强支护。
The side wall central section, the arch foots and the vault are key parts of the tunnel where should be strengthened to support.
现场对隧道周边位移收敛值、拱顶下沉值和地表下沉值进行监测。
Furthermore, peripheral displacement convergence and settlement of vault and ground surface are monitored on-site.
在建兴高速樊屯隧道施工过程中，对地表沉降、拱顶下沉、围岩收敛等进行了监控测量。
The ground surface settlement, crown settlement, convergence of surrounding rock, etc, are monitored and measured during the Fantun tunnel construction of Jianxing Highway.
应用有限元数值方法，对连拱隧道“三导洞法”施工时围岩和结构的受力、变形规律进行了分析。在两正洞拱部施工的时候，左右洞拱顶沉降约占最终沉降的70%。
The regularity of stress and strain of surrounding rock and support structure when using(3-heading) excavation method to construct double-arc tunnel is carried out by FEM numerical method.
