隧道软弱围岩开挖技术

Tunneling Technique for Soft Surrounding Rock

公路隧道建设过程中最常见的地质为软弱围岩,若施工工艺不当,很容易影响隧道施工安全。在隧道建设过程中,必须要将每一步工作都落实到位,只有这样隧道工程才能顺利完工。论文结合某实际工程案例,研究在公路隧道工程的建设中,三台阶预留核心土法在软弱围岩中的应用,以确保隧道工程建设的安全性以及稳定性。

In the process of highway tunnel construction, the most common geology is soft surrounding rock. If the construction technology is improper, it is easy to affect the safety of tunnel construction. In the process of tunnel construction, every step of work must be put into place, only in this way can the tunnel project be completed smoothly. Based on a practical case, this paper studies the application of three steps reserved core soil method in soft surrounding rock in the construction of highway tunnel to ensure the safety and stability of tunnel construction.
