783119 FRICTION ROCK STABILIZERS - A NEW ROCK REINFORCE-

ME~T M W ~ K m Scott, J J In: Monograph i on Rock Mechanics Applications in Mining (New York: AIME, 1977), P242-249 Describes the friction rock stabiliser (Split Set), relxrts pullout tests, time depemdent rock deformation effects, comparison with resin grouted bolts, lab teats of shear resistance and of atra/n distribution, a~d discusses its compatibility with basic rock mechanics principles.

Groundwater problems 78312o CROSSING A WATER-LADEN FAULT Bruni, F Turm Tunnlg~Vl0, N2, 1978, P33-35 In the Gram Sasso tunnels of the Rome-Alba Adriatic motorway, a fault formed an interface between highly degradable materials and impermeable materials. In the latter water was present umder the high pressure of 6 MN/sq m. This a r t i ~ e describes the investigations carried out and the construction amd drair~ge measures adopted to make this critical crossing.
