Bad ground, with mar~ faultsI a r d large i~flows of water have caused difficulties in the driving of the 21ks long Walgau water ttumel (usir~ a full face T~M). Rock suppm't methods being used imclude: rock bolts anl/or mesh ami shotcrete~ and steel ribs. Only one collapse, at the side of the ttumel, occurred: the void was filled with concrete ard steel rings installed. 832082 SLIDING RESISTANCE OF J A C ~

Pilot boring, and grouting to strengthen loosened zones were carried out. Difficulties overcome included four inflows of sea water ard high soll pressures.

The only m~Jor setback so far has been an inflow of groundwater where a dip of unstable sand arh ballast interrupted the clay layer.

Pt~I Rotterdam: A. A. Balkema, 1981 An experimental tunnel excavated through a stiff silty clay (overconsolidated glacial till) has been extensively instrumented. The instruments provided data on a complete three-dimensional displacement field around the tunnel. From insitu measured displacements, displacement gradients and thus strains have been calculated. The derived maximum shear strain field has been compared with stress-strain testing data for the till amd used as a failure criterion to investigate the process of mobilization of shear strength and development of failure zones around the tunnel. The deduced mechanism of mobilization of shear strength provides an insight into the arching process aroumd the tunnel and explslns the low pressures observed on lining of tunnels in till. Auth.
A method is ;resented for tunnel liming design based on ultimate load theory. The design loa~s are computed from suitable load factors which are based on failure of the tunnel lining. The effect of the herding rigidity, ratio cf vertical to horizontal pressures, support conditions of the tunnel anl effect of soil stiffhess are all considered. 832086 PRECAST REINFORCED CONCRETE LINIRD OCMPETES WITH NATM Wagner, H Tumm Ttmnlg, Vl~, NS, Sept 1982, ~5-18 The introduction cf ;recast sim@le shelled waterproof re-inforced cor~rete linings with Is;roved sealing systems has made this type of llnimg more economically viable compared with shotcrete and in situ concrete linings. 832087 JERSEY TUNNEL OVerCOMES THE LEGACY OF OLD ~RICK SEWERS Martin, D Tumm Tmmmlg, VI~, NS, Sept 1982, F23 A case stmdy of a ccm!m~essed air drainage tunnel on Jersey, D~K. Shaft sirAkimg and t1~m~elling was through salt yellow silt, with the turmel sited very near the seafront in totally waterlogged grourd. High rise tides also caused complications.
