Excerpt

The rock quality designation (RQD) is widely used around the world as an important index and reference for rock mass quality evaluation (Deere 1963). Many engineers have frequently used the RQD to determine the soundness of rock masses in combination with their own experience (Choi and Park 2004). Therefore, the RQD, which is inexpensive and easy to determine, is of great interest in construction applications in rock mass engineering (Azimian 2016). …
