Experience summing-up of tunnel collapse treatment

文章对介绍隧道塌方为实例,通过加固未塌方地段,在保证施工生产安全的前提下,对塌体进行注浆、塌腔进行回填,然后在一步步进行塌方段开挖,最后顺利通过塌方段的细致描述,为以后隧道施工出现类似问题提供一定的参考。

In this paper, in combination with Tunnel volume collapse treatment, the cause of the large volume collapse is analyzed, the collapse treatment principle and the treatment scheme applied are presented. The results indicate that the collapse treatment is quite successful.
