STRESS SENSITIVITY OF SEISMIC PULSE VELOCITY AND RISE TIME IN A ROCK-LIKE MATERIAL
It is shown in a large scale model that the seismic pulse rise time is far more sensitive to a change in both uniaxial and biaxial stress fields than is the velocity of pulse propagation. This rise time sensitivity makes the measurement of pulse rise times a promising method for stress surveillance around underground excavations. Rock failure has also been shown to cause a significant increase in the pulse rise time. (TRRL)
