Prediction method of falut pole ahead of the tunnel face using monitoring center vector

摘要

The present invention relates to a method for predicting the fault zone of the excavation front by using a convergence displacement of the tunnel, more particularly by introducing a new concept of measuring cross-sectional center point vector to the three-dimensional behavior aspects of the tunnel it appears at different fault zone pass interval analysis and by using the results of this analysis relates to a method for predicting the fault zone in the front face mapping of the actual tunnel construction site. ; Tunnel fault zone predicting method in the tunnel face the front of the invention is the measurement section movement of the center point of a When the center point of the three-dimensional displacement coordinates shown in the Temple and left of the tunnel cross-section, a right side wall as the measurement cross-section center point (MCC) tunnel excavation advancing direction a method for predicting the fault zone in the tunnel face the front by using a measurement cross-section center point vector (MCV), which is defined by a vector, (a) step of analyzing the orientation of the MCV by fault zone oblique direction collect analysis data for the virtual tunnel .; (B) obtaining the MCV of the excavated tunnel for the construction site to be predicted the fault zone of the front face mapping; And, (c) using the data analysis in the step (a) evaluating the fault zone oblique direction for the orientation of the MCV of the tunnel construction site obtained in step (b); and characterized in that comprises a. ; Tunnel face, metrology section, vector, fault zone, forecasting, and changing patterns
