SYSTEM AND METHOD FOR PREDICTING DISCONTINOUS FACE OF TUNNEL WORKING FACE

PURPOSE: A discontinuous surface estimating system for tunneling and a method thereof are provided to remove risk factor in construction by the estimation of the front surface of an excavation blind end or the rear portion of the neighboring tunnel. CONSTITUTION: A recognition unit(103) recognizes 3D(Dimensional) block of the discontinuous surface of dark spots distributed in the blind end. The extracting unit(104) analyzes 3D block, extracts unstable blocks, and schematizes the unstable block into 3D drawing. The estimator(108) analyzes joint distribution of the dark spot in an excavation portion using the 3D drawing of the unstable block and estimates discontinuous surface distribution of the excavation portion based on analysis. The recognition unit measures the 3D arrangement structure of the discontinuous surface of the dark spot distributed in the blind end using the 3D image of the blind end.
