This paper quantitatively compares predicted amd encountered shear zone size amd location for tunnels in the Colorado Belt. 782068 ENGINEERING INSPECTION AND APPRAISAL OF ROCK TUNNELS Kenforaki, F S; Bischoff, J A Proc Rapid Excavation anl Tunnelling Conference, Las Vegas, 1~-17 June 1976, PSl-100 Stresses the desirability of geological and construction data for tunnels and discusses
a methodical recordimg of data concerni~ general geology, shears, fracture Orientations, spacimg, persistence, rock classification, water co~lition~ shear frequency, excavation method, blasting l~ocedure, and rock stabilization and suppc~t ~thods, combir~d with a photographic record. This can be completed by experienced engine,s and geologists at the rate of over I000 feet of tunnel per shift. 782069 SLURRY SHI~W~ METHOD IN JAPAN Takahasi, H; Yamazaki, H Proc Rapid Excavation and Tumr~llir~ Conference, Las Vegas, 14-17 June 1976, P261-277 Gives an outline of the slurry shield method and describes the machine itself. Discusses how the cutter face is supported by the pressurised slurry amd the slurry treatment. Fir~!ly, shows how t ~ l l i m g work is controlled, anl discusses some recent IroJects. 782070 WASHINGTON METRO'S TOPLESS TUNNELS Kuesel, T R Proc Rapid Excavation and Tunnelling Conference, Las Vegas, 14-17 June 1976, P296-310 Discusses the excavation of 4 tunnels through a mixed face, with a clay invert and a waterlogged sand crown, and the use of grout i~ection to stabilise. 782071 CONSTRUCTION OF S H I N - K ~ O N TUNNEL ON SANYO SHINKANHEN Sato, Y; Shinoda, Y; Fu~ita, H Proc Rapid Excavation and Tunnelling Conference, Las Vegas, 14-17 June 1976, P335-354 Discusses the excavation of the 880m undersea part of the tunnel through a fault zone 30m wide, approximately 30m beneath the sea bed. 782072 FULLY MECHANISED TUNNELLING MACHINE AND ~ T H O D TO COPE WITH THE WIDEST RANGE OF GROUND CONDITIONS - EXPERIENCES WITH A HARD ROCK PROTOTYPE MACHINE Granderi, C Proc Rapid Excavation and Tunnelling Conference Las Vegas, 14-17 Jure 1976, P355-376 782073 EXCAVATION METHODS FOR LONG HIGHWAY TUNNELS AND VENTILATION S H ~ S IN THE SWISS ALPS Pfister, R E Proc Rapid Excavation and Tunnellimg Conference, Las Vegas, 14-17 June 1976, P377-397 Reports experience in construction of the Gotthard and seelisberg tunnels. Methods of excavation include excavation of shafts in herd rock by conventional drilling ard blasting, excavation by ripper-tooth excavator in marlstone, shield protected heading in loose material amd soft rock, and tunnel and shaft linimg, both by poured concrete and by l~efabricated elements. A critical review of the success of these methods is now made after a five year construction period. 782074 EFFECT OF RAPID WATER PRESSURE FLUCTUATIONS ON UNLINED WATER TUNNEL ~ABILITY Lamg, T A; Kendorski, F S; Chewla, K S Proc Rapid Excavation and Tunnelling Conference, Las Vegas, 14-17 June 1976, I~17-429 Unlined water tunnels have often been used as pressure comduits for hydroelectric projects.
