Title:
VERIFICATION METHOD AND VERIFICATION DEVICE FOR ELASTIC WAVE PROPAGATION CHARACTERISTICS
Document Type and Number:
Japanese Patent JP2021123888
Kind Code:
A
Abstract:
To provide a verification method and a verification device for elastic wave propagation characteristics that can easily and repeatedly verify the relationship between the polarity reversal of reflected waves and rock properties with high accuracy.SOLUTION: A verification method for elastic wave propagation characteristics of rock or ground comprises the steps of generating an elastic wave inside a test piece 12 formed by connecting a plurality of different types of rock materials or ground materials 22A to 22D whose internal elastic wave velocities are known, receiving the direct wave and the reflected wave of the generated elastic wave by a sensor 16, and verifying elastic wave propagation characteristics based on received waveform data.SELECTED DRAWING: Figure 1
