STABILITY OF THE JOINTED ROOF IN STRATIFIED ROCK

In this paper, a finite element program that can simulate non-linear joints and geometry non-linearity was developed and a large scale test rig was used to study the mechanism of the voussoir beam. The deformation and failure mechanism are analysed and equations and methods for strength estimation are proposed. Furthermore, the effects of multiple mid joints and applications to the stability analysis of a jointed roof are presented. (A) This paper was presented at the 34th U.S. Symposium on rock mechanics, 27-30 June 1993, University of Wisconsin-Madison. For the covering abstract see IRRD 863389.
