821088 PLANNING AND CONSTRUCTION OF THE TOHOKU SHINKANSEN UENO SHIELD TUNNEL, D I ~ OF 13M Yamaguchi, Y; Matsuahita, H Proc 5th Rapdd Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, VI, P241-253. Publ New York: AIME, 1981 The design and geology of the Ueno shield tunnel is described, together with the design of the segment ring and the hand mining shield used. Soil stabilisation methods included freezing, compressed air working, ground water lowering and chemical grouting. Examples of protection of surface structures by umderpinnir~ and by construction of a bearing slab are given. 821089 E~'~'~"TS OF SHIELD TUNNELING OVER SUBWAYS Hansmire, W H; Parker, H W; Ghaboussi, J Proc 5th Rapid Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, V1, P254-276. Publ New York: AIME, 1981 There are two critical crossings of the proposed tunnel for the Red Hook Intercepting Sewer, ~rooklyn, New York, in soil above existing subways. The geology of these crossings is described and finite element simulation used to predict tunnelling influence. Construction methods for the crossings were then modified, and the crossings monitored during excavation. Field measurements from this are quoted and compared with predicted values, which proved to be rather high. The tunnelling influence was considered to be due to both soil removal amd the shoving of the shield.
8210~ PIPE JACKING TECHNIQUES FOR SMAI~ SOFT GROUND TUNNELS Allen, M E Proc 5th Rapid Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, VI, P289-306. Publ New York: AIME, 1981 Discusses pipe Jacking techniques in the context of standards for pipe used, the use of mechanised shields and wheel-type tunnelling machines, muck haulage, t~e Jacking system, a bentonite slurry system and tunnel guidance. 821091 SMALL DIAMETER TUNNELS - AN OVEEVIEW Arnold, C H Proc 5th Rapid Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, V1, P322-331. Publ New York: AIME, 1981 Reviews the history, excavation and support methods, tunnel lining, and economics of small diameter (up to 4m) hard rock, soft ground and subaqueous tunnels. 821092 FULLY MECHANIZED SMALL DIAMETER TUNNELLING TECHNOLOGY Kan~natsu, T; Kusakawa, H Proc 5th Rapid Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, VI, P332-341. Publ New York: AIME, 1981 Describes the development of a fully mechanlsed small diameter shield tunnelling method able to cope with diameters as low as 600n~n. A case history for this method to produce a 800ram diameter tunnel is outlined.
821093 MIXED FACE TUNNELLING. SOME DESIGN AND CONTRACT CONSIDERATIONS Sutcliffe, H Proc 5th Rapid Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, VI, P~5-356o Publ New York: AIME, 1981 Discusses the nature of mixed face tunuelling suggests courses of action in planning, exploration, design and contract conditions to minimise problems inherent in this type of excavation° Auth. 82109~ MIXED FACE TUNNELING IN URBAN SETTING Desai, D B; Ku, C C Proc 5th Rapid Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, V1, P357-381. Publ New York: AIME, 1981 Describes all aspects of the tunnelling of a section of the Northwest Line of the Baltimore Region Rapid Transit system, Maryland, USA, from subsurface investigations o~ards. 821095 MIXED FACE TUNNEL EXCAVATION USING FLOATING CROWN BAR AND MODIFIED SPILING METHODS Puza, D E; Borggaard, R C; Bhore, J S Proc 5th Rapid Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, V1, P383-389. Publ New York: AIME, 1981 Outlines the selection and use of suitable mining methods for the 148m long mixed face tunnelling section of the Red line Extension, Semerville, Mass, USA. Describes the rejection of shield tunnelling on economic grounds, the use and rejection of the Floating Crown Bar System due to support problems, and the eventual selection of a modified spiling method. The use of cement, chemical and compaction grouting to prevent ground water inflow and building settlement is described. 821096 MARTA'S BROAD STREET TUNNELS Kuesel, T R; Parker, H W Proc 5th Rapid Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, V1, F393-408. Publ New York: AIME, 1981 Describes the selection and use of a shield and compressed air as a suitable method for the mixed-face tunnelling required for a section of a pair of twin single-track tunnels, as part of the Metropolitan Atlanta Rapid Transit Authority transit system, Atlanta, Georgia, USA. 821097 APPLICATION OF THE NEW AUSTRIAN TUNNELING METHOD UNDER VARIOUS ROCK CONDITIONS John, M Proc 5th Rapid Excavation and Tunneling Conference, San Francisco, 3-7 May 1981, V1, I~09-426. Publ New York: AIME, 1981 Describes several case studies for road tunnels of cross sectional area 70-100sq m to show the use of the NATM for a range of rock conditions. The rock conditions and construction methods for the following are described: Arlberg Expressway Tunnel (mica schist), Lebenberg Tunnel (dolomite and clay slate), Dalaaser Tunnel (soil, clay slate, limestone plus fault zones), PerJen Tunnel (quartz phyllites, dolomite, limestone), and Pfander Tunnel (marl and clay marl ).
