关于软弱围岩中隧道超前支护施作的新构想

New Conception on Construction of Tunnels in Weak Surrounding Rocks

阐述了隧道软弱围岩段洞身开挖后的变形机理,有针对性地为隧道穿过软弱围岩提出了超前支护施工的新构想,较好地解决了施工中可能出现的隧道塌方问题,对隧道施工技术推广应用具有参考作用。

This paper expounds the deformation mechanism of the tunnel in the soft surrounding rock section of the tunnel, and proposes a new concept for the advance support construction of the tunnel through the weak surrounding rock, which better solves the possible problems in the construction.The tunnel collapse problem has a reference role in the promotion and application of tunnel construction technology.
