METHOD OF PREDICTING GEOLOGICAL CONSTITUTION OF NATURAL GROUND

PROBLEM TO BE SOLVED: To easily grasp the geological constitution of the natural ground with high accuracy as a part of routine construction management abreast with excavation work without needing a special geophysical exploration measuring apparatus. SOLUTION: An arbitrary number of observation points are set in a peripheral region of an open cut part of the natural ground, and a displacement measured data is acquired from the measured result of displacement of the observation points before and after blasting excavation. In a three-dimensional analytical model reflecting the excavation progress situation, block allocation is performed beforehand based on geological distribution, and under the condition that a ground constant is a constant value in each block region, inverse analysis is performed with the displacement measured data as a given condition to identify the ground constant of the natural ground for every block region.
