Tunnel lining methods
42A 871318 Two examples of design of sports halls in rock caverns Roininen, S: Poyhonen. R: Leinonen. J Proc International Symposium on Large Rock Caverns. Helsinki, 25-28 August 1986 VI. P209-218. Publ Oxford. Pergamon Press. 1986
871322 Conference of the Institute of Shaft Drilling Technology m Las Vegas (In German and English) Sabels. B Gluckauf V122. N16. 21 Aug 1~'6. P1068-1069 .zerman: P303-304 :english )
Two projects involving underground sports halls air raid shelters m Finland are described. One is in gneissic rock. the other in granodiorite. Field investigations included engineering geological mapping, diamond core drilling and the measurement of in situ stress. Finite element analysis was extensively used as a design tool.
The 15 papers delivered during 14-16 May, 1986 are very briefly summarised. Topics included: raise boring with a pilot hole: shaft and tunnel boring; shaft lining; borehole alignment: and conventional shaft sinking.
871319 Holmlia sportshall and swimming pool in rock planning, construction, use Rygh, J A Proc International Symposium on Large Rock Caverns, Helsinki, 25-28 August 1986 V1, P219-230. Publ Oxford" Pergamon Press. 1986 The construction of an underground sports hall/civil defence shelter in Norway is described. Aerial photography and core drilling were used to find a suitable location in the gneissic rock. Excavation was by drill and blast, with bolts and shotcrete for support. Sports facilities are situated in buildings constructed within the cavern, to facilitate atmospheric control.
Radioactive waste disposal 871320 Simulation of fluid flow and energy transport processes associated with high-level radioactive waste disposal in unsaturated alluvium Pollock, D W Water Resoar Res I:22, N5. May 1986, P765-775 The basic long term (200 year) effects of high level radioactive waste disposal on the movement of water and energy in unsaturated alluvium are analysed. The model describes one-dimensional, vertical, coupled transport of energy, water (liquid and vapour), and dry air around an extensive repository located 100m below land surface. Distributions with time of temperature, saturation, and gas flux around the repository are presented.
Underground construction methods 871321 Microtunnelling: no pipe dream Thompson, J C Civ Engng, N Y 1:56, N8, Aug 1986. P56-59 The concept of microturmelling, driving tunnels conventionally of diameter 25-100 cms, is introduced and microtunnelling machinery, especially that suited for use in bad ground, is briefly reviewed. New pipes and joints developed in conjunction with these pipe jacking systems are described, and the economics of the method considered.
871323 Giant machines cut way for French rail Cooper. P New Civ Engr N707. 18 Sept 1986 P27-29 Two 4.8kin bores for the TGV are being excavated in sand Consolidation of the sand by grouting was ruled out on cost grounds. Tunnelling, using a 9.25m diameter hydroshield, is currently progressing at 10m/day. The machine has provision for a compressed air bubble between the bentonite shield and the membrane, which allows fine regulation of face pressure and access to the face if boulders are encountered. The lining is by concrete segments, produced at a computerised plant, which matches section size to changes in gradient or curvature.
871324 Cavities and tunnels in hard rock by thermal spaltation Williams, R E Underground Space V9, N5-6. 1985 P273-275 Thermal spallation is an established method of cutting granite or drilling other hard rocks. Development work for the Hot Dry Rock Geothermal Program showed the potential of this techniq we to produce relatively large diameter holes with existing equipment, and suggested further applications. The spallation process and equipment now available are described, and schematic representations of cavity excavation and a spallation tunneller are provided.
871325 Tunnel lining methods Babendererde, S Underground Space V9. N5-6 1985, P276-279 There are four commonly used methods for lining tunnels in soft ground conditions: shotcrete; in situ concrete behind a blade shield; precast units; or extruded concrete. The techniques, equipment, materials and economics of each are examined.
871326 Shaft sinking in the Hemlo Gold District White, P Proc of the 1985 Rapid Excavation and Tunneling Conference, New York, 16-20 June 1985 V1, P192-204. Publ New York." AIME. 1985 The Hemlo Gold District, located on the north shore o f Lake Superior, was discovered in 1981 and will become one of the largest gold mining camps in Canada. The types of shaft sinking equipment and technology being used by contractors in constructing the required shafts to depths below 10OOm are described. The principal shaft design criteria, types o f shaft sinking machinery and relevant manpower altocauons are discussed.
