PRE-FAILURE DILATANCY AND THE STRESS DISTRIBUTION IN A CLOSELY JOINTED ROCK MASS

The behaviour of dense sand, a rough joint, and models representing closely jointed media lead to the observation that, well before failure is reached, these materials increase in volume, i.e. The onset of dilatancy occurs before the peak strength is reached. This paper investigates, in a rather simple manner, the effect of this pre-failure dilatancy on the stress distribution in a rock mass beneath a surface loading and adjacent to a pile. The number of the covering abstract of the congress is TRIS no. 385148. (TRRL)
