摘要
公路隧道塌方事故有时难以避免,文中通过分析一工程实例的塌方事故处理,总结该类事故处理的经验。实例表明,应加强施工防排水,避免进一步软化围岩;注浆加固、补缝、加设钢拱架、补打锚杆处理软弱围岩公路隧道塌方是行之有效的措施,同时应加强监测。
Sometimes it is difficult to avoid highway tunnel collapse accident, the paper analyzes the incident handing of the project example landslides and sums up the experience.Example shows that the construction of drainage defense should strengthen,to avoid further softening rock.Grouting reinforcement,linking,adding steel arch and bolt-fight are effective measures to deal with soft rock highway tunnel Collapse. At the same time, monitoring should be strengthened.
