Reports tunnelling for an irrigation project in south-eastern Peru, involving 37 tunnels of varying length, most of them at 3700m above sea level.
silts and limestone boulders ~hich have a tendency to creep. Excavation and shotcreting of the frozen rock are described briefly. 796101 DECIDING ON THE EXCAVATION .METHOD FOR A TUNNEL FROM THE GEOLOGISTS' POINT OF VIEW Wanner, H Undergrouni Space, VJ, N6, May-Jur~ 1979,

No damage was observed below calculated surfsce accelerations of 0.2g. A critical assessment of the study is employed to establish what research is necessary to refine analytical approaches. Auth.
796o96 COPING WITH DIFFICULT GROUND ON THE FULLFACE MECHANISED 'TUNNEL DRIVES AT KIELD~R Nicholson, K Tunn Tunnlg, VII, NS, June 1979, P55-57 Describes 3 methods used in bad ground in the K l e l d ~ Tunnels, northern Er~amd. (i) A top heading is driven from the s u p ~ platfc~nn over the roof shield to the face of the machine-cut tunnel, axcavating all loose rock and installing temporary arch supports. (2) Construction of a D-section at the face. (3) Conventional drive in front of the machine. None of these methods necessitated the withdrawal of the tunnelling machine.

Particular reference is made to papers on the mud shield process, on tunnel design, environments, anl contractual practices. See also: 796092
Discusses the limits of mechanical boring in terms of rock mass drillability, rock abrasiveheSS, bracing of the boring machine, stability of the rock mass, deformation of the tunnel and extreme conditions of temperature, gas or water, amd gives examples from Swiss practice where these limits have been exceeded. 796102 TUNNEL STABILITY BY THE METHOD OF CONVERGENCECONFINEmeNT.

Publ Granada: Asoclacion Nacional de !r~enleros de Minas, 1978 Describes the project to construct an aqueduct from Mornos Dam in central Greece to Athens, which requires tunnelling through limestone with major surface karst features. The influence of hydrogeological features on tnnral construction amd operation is discussed.
