Abstract
Tunnel collapse is one kind of common ground collapse calamity recently, it is due to the collapse of civil air-defense construction which was excavated many years ago and never had been repaired. In order to reduce calamity losses, and carry out the control project effectively, the detailed calamity exploration need to be done. The distribution of tunnel collapse calamities in the work area was identified based on the related geological data analysis and the ifeld investigation. And the authentic burial situation and the location of the tunnels were determinate by all kinds of geophysical methods, such as exploration, drilling, cone dynamic penetration and trenching.关键词
