... is to shortly introduce the surveying process and interpretation of the 3D optical displacement measurement methodology. Our research is related to geodetic measurements which were carried out in the repository chambers and some exploratory tunnels. The mentioned exploratory tunnels crossed through fault zones...

It also reports the studies made so far of displacement measurement for an urban tunnel excavated by NATM, for steel segmental rings in a tunnel excavated by TBM, and of measurement while burying...

... At August 27, 1999, at Nakutaki Area in Yamaguchi City, Japan, a rock slope of an old granite quarry collapsed and some of the 3,300 m 3 rubble covered a road along the slope. A laser displacement measurement was employed to monitor an unstable rock mass left on the slope, to secure repair...

..., and it has installed as the reinforcement system established. The deformation of the slope rock mass and the stress state of the reinforcing system arc measured from a network of measuring points. A summary of the installed monitoring network is as follows: surface displacement measurement of the slope...
