METHOD AND SYSTEM FOR EVALUATING PHYSICAL PROPERTY OF BEDROCK, PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To efficiently acquire an evaluation result of excellent precision. SOLUTION: This method/system for evaluation comprises processes for: executing an original position test and elastic wave velocity measurement for other peripheral bedrock to acquire a modulus value of deformation and an elastic wave velocity; drawing out a multiple regression correlation expression based on the modulus value of deformation, the elastic wave velocity and geological property information of the other peripheral bedrock; applying geological property information of an evaluating bedrock to the multiple regression correlation expression to estimate a modulus value of deformation in the evaluating bedrock; executing the elastic wave velocity measurement only for one measuring line in the evaluating bedrock to acquire the modulus value of deformation in the evaluating bedrock; recognizing strength or a change thereof in the evaluating bedrock based on the elastic wave velocity of the evaluating bedrock, and collating it with a prescribed determination reference to determine the necessity of individual investigation for a modulus of deformation; and determining the estimated modulus value of deformation as the modulus value of deformation in the evaluating bedrock, when the individual investigation is determined to be unnecessary.
