Abstract
Usually, a geotechnical investigation along a tunnel axis is based on destructive borings, pressuremeter profiles and drilling with undisturbed samplings for laboratory tests. The subsurface geological section in the area of the tunnel is often densely investigated by many drill holes, with a spacing about 40 to 50 meters.
