説明
The present paper describes a new technique for estimating initial stresses in rock mass by measuring phase velocity of ultrasonic (elastic) waves in a specimen shaped from the bored core. The technique is supported by the following facts observed in the tests carried out for andesite, basalt, granite and sandstone specimens.<br>1) Phase velocities of both longitudinal and shear waves traveling in the perpendicular direction to the loading axis in the uniaxial compression test change considerably at the pre-experienced maximum stress.<br>2) The pre-experienced maximum stress is remembered at least one week.<br>3) The phase velocity of shear wave polarized in the perpendicular to the loading direction is not affected by the pre-existed stresses in other directions.
