摘要

The Authors thank the Discusser for providing discussion on a matter that seems so straightforward, and therefore possibly banal, but that yet causes considerable difficulties in practice. We note that we are in agreement on all aspects except the concept of the 'shuffling' of the core extending to the records of Total and Solid Core Recovery (TCR and SCR) and Rock Quality Designation (RQD) presented on the borehole log; the treatment of Fracture Spacing is not mentioned in either the paper or the discussion, but this argument would extend to that index also. The Discusser cites BS5930:1999 (BSI 2010), where the definitions of these indices are given as 'core recovered to length of core run'. We would go further and cite Clause 47.2.6.1 (BSI 2010), where a requirement is given that 'the log should be a record that is as objective as possible of the ground conditions at the borehole position before the ground was subjected to disturbance and loss by the boring process'.
