Determination of Uniaxial Compressive Strength of Limestone

, 2019
Najčešće korišten parametar u stijenskom inženjerstvu je jednoosna tlačna čvrstoća (UCS). Često se procjenjuje na terenu ili pomoću korelacija s indeksom čvrstoće u točki predloženih od strane različitih istraživača za određen tip stijene.

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

Deep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...
