Abstract:

The rescue of 6 collapse incidents occurring during the construction of mountain tunnels is compared and summarized; the features of the collapse incidents, the rescue methods and the rescue results are analyzed; factors on which the determination of the rescue tunnels and the rescue methods depend are summarized on basis of several collapse incidents under different conditions and effective recommendations are made. The paper can provide reference for the determination of the rescue methods for similar collapse incidents in the future.
