摘要

Faults and karst zones, aquifers, cavities, and artificial as well as natural obstacles represent major hazards to tunnel construction. It is especially where mechanized means are used for driving tunnels that strata boundaries or faults encountered unexpectedly can lead to costly damage to machinery and injury to personnel and may even bring tunnel drives to a halt. To counteract this situation, a variety of techniques for reconnoitring in advance of tunnel construction have been developed in recent years.
