ROCK MASS DYNAMIC TESTING APPARATUS

摘要

An apparatus of testing dynamic physical properties of a base rock is provided to use joint base rock samples in various sizes and simultaneously measure various dynamic physical properties of the samples. An apparatus(300) of testing dynamic physical properties of a base rock includes a sample fixing part fixing the bottom end of a sample with a fixing block, a pressure loading part(120) applying air pressure to the inside of an air chamber in which the sample is located, a rotary excitation part(130) delivering an exciting force of the circumferential direction of the sample, and a loading part(140) for applying a load to the sample in the axial direction.
