SWELLING ROCKS AND THE STABILITY OF TUNNELS

A characterization of swelling rocks is presented. The mechanism of the swelling is described by means of the physico-chemical effects and rheological effects: creep, the elastic recovery and dilatancy. The importance of mineralogical and physico-chemical tests is stressed. Some rheological testing methods are suggested. An analysis is given of the routine swelling test. Constitutive equations for dilatancy behaviour in two dimensions and a calculation of the dilatant zone around a tunnel are described. The number of the covering abstract of the congress is TRIS no. 385148. (Author/TRRL)
