FIELD CASES USING KEY BLOCK THEORY. LARGE ROCK CAVERNS - PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM, HELSINKI, FINLAND, 25-28 AUGUST 1986. VOLUME 2

Blocks formed by joint intersections above underground openings are divisible into classes of hazard using block theory. This paper shows an analysis of critical blocks - key blocks - taking account of the stabilizing effect of field stresses and dilatancy on block faces. Several case histories lead to the conclusion that a small field stress can stabilize blocks that would otherwise tend to fail. For the covering abstract of the symposium see IRRD 810647.
