BEDROCK EVALUATION METHOD
PROBLEM TO BE SOLVED: To provide a bedrock evaluation method capable of quantitatively evaluating a bedrock at high accuracy.SOLUTION: A bedrock evaluation method includes: a physical property value acquisition step S11 for acquiring a physical property value of a specimen sampled from a surveyed ground; a reference value setting step S13 for setting a bedrock evaluation management reference value based on the physical property value and a management reference physical property value that represents a color value or a magnetic susceptibility value correlating with the bedrock evaluation management reference value; a measurement step S22 for drilling the surveyed ground and measuring the color value and the magnetic susceptibility value of drilling debris at each depth of drilling; and a bedrock evaluation step S23 for evaluating the bedrock at each depth of drilling by comparing the measured color value or magnetic susceptibility value of the drilling debris with the management reference physical property value.SELECTED DRAWING: Figure 1
