THE ROLE OF STRUCTURE AND SOLID MECHANICS IN THE DESIGN OF SURFACE AND UNDERGROUND EXCAVATIONS IN ROCK

This paper studies the effect, on the design of surface and underground excavations, of the characteristics of the rock in which they are made, and investigates in detail three techniques in evaluating these characteristics. These are an empirical approach, based entirely on experience, a limit equilibrium approach based on the strength characteristics of the rock mass, and a stress analysis approach based on both the deformation and strength characteristics of the rock mass. Subsequent sections of the paper comprise a brief review of the state of the art of engineering for excavations in rock including the characteristics of rock masses geological investigations for excavations and rock classification systems. It is shown that, provided sufficient geological and engineering data about the rock are obtained, it is possible to estimate the behaviour of an excavation under given loading conditions. /TRRL/
