Technical paper: CIRIA instrumented drilling trials – background and progress

E T Brown, BE, MEngSc, Pho, CEng, MICE, MASCE, FGS. This paper was first published in GE’s Janaury 1979 edition.

Introduction

The Construction Industry Research and Information Association (CIRIA) is currently conducting a series of instrumented ground investigation drilling trials at Rogerley Quarry, Frosterley, Co. Durham. These trials, which form part of CIRIA’s underground construction research programme, aim to investigate the practicability and utility of using drill rig instrumentation to record drilling variables during tunnelling site investigations. The primary concern of the group sponsoring the trials is to develop techniques that can improve the quality and quantity of data made available in pre-tender tunnelling site investigations.

This Paper summarises the background, organisation and development of the project, and presents and assesses some of the preliminary results obtained.
