Determination rock quality designation RQD basis on joints


Keykha, Hamed A. and Kim Huat, Bujang (2011) Determination rock quality designation RQD basis on joints. Electronic Journal of Geotechnical Engineering, 16 (bund. E). pp. 522-526. ISSN 1089-3032


This paper is a critical review on the role of joints in determination of rock quality designation (RQD) in observation plane. It show that the analyzing joint sets with using simple method like get data from surface of rock mass, can be effective to indicate RQD. It is estimated by counting joint volumetric Jv and compared with weighted joint density (WJD).
