Determination and applications of rock quality designation

01/06/2016· Since in many cases rock quality designation (RQD) is the only rock mass classification index available, this paper outlines the key aspects on determination of RQD and evaluates the empirical methods based on RQD for determining the deformation modulus and unconfined compressive strength of rock masses. First, various methods for determining RQD are presented and the effects of different

What is RQD (Rock Quality Designation) and How to

Rock quality designation RQD = (SUM(length of sound pieces >100mm)/Total core run length)x100. SUM(length of sound pieces >100mm) = 250+190+200 = 640mm. Therefore, RQD = (640/1200)x100 = 53% which is fair quality rocks, i.e. rocks are moderately weathered. Uses of Rock Quality Designation (RQD) in Construction

Computing in-situ strength of rock masses based upon

01/10/2015· Rock quality designation (RQD) 1. Introduction. Mechanical properties of rock mass interpreted by engineers in field differ significantly due to the micro-disconformities of strength. The failure theories indicate that the strength is a thermodynamic state depending upon isotropic pressure, which is insignificant at the opening of the discontinuity and reaches a peak at a location of stress
