THE CONTROL OF SMALL SCALE INSTABILITY IN ROCK EXCAVATIONS - A REVIEW

The mechanisms of small scale failure in rock excavations including sliding, toppling and collapse are reviewed. Factors that influence stability such as the orientation and strength properties of geological discontinuities, and the presence of groundwater are discussed. A systematic approach to geotechnical investigation and design, construction evaluation and post-construction inspection is suggested, recognising that the extent of small scale instability can seldom be accurately predicted before construction. A variety of treatments to stabilise slopes during or following construction are identified for each failure mechanism. Finally, means of protection are outlined for situations where stabilising treatments are impractical or ineffective. (Author/TRRL)
