Wave Velocity and Power Spectral Density of Hole-Containing Specimens with Different Moisture Content under Uniaxial Compression

The gas drainage borehole is a typical hole-containing structure, and its failure is similar to the hole-containing specimen. To study the characteristics of wave velocity and power spectral density of the hole-containing specimens with different moisture content, an ultrasonic test of the hole-cont...
