70A 862246 Culverts: Analysis of soil culvert interaction and design Transportation
Research Record N1008, 1985, 122P
Sixteen papers are presented. Fifteen deal with various features of design, performance or soil structure interaction for buried structures (pipes, conduits, tunnels) or bridie arches. The remaining paper is concerned with the mechanical properties of grouted sands. Avail: TRB. NAS, 2101 Constitution

Soil-structure interaction is reported for two shallow-buried elliptical steel culverts, one with a relieving slab to reduce liveload effects under vehicular loading. Instrumentation used and test details are described. Comparison of results showed that the slab led to a reduction in live-load thrusts and moments in the steel shell. A simplified procedure is given to explain this phenomenon. 862248 Deflections and strains in buried FRP pipes subjected to various installation conditions Moser.

862251 Bochum Ring Road: planning and choice of construction method Steineheuser, G; Maidl, B Rock Mech V18, N2, April-June 198.5, P63-76
An account of the investigation for and construction of the tunnels for West Tangent of the Ring Road in Bochum. The classical stoping method was chosen as the cheapest and quickest. In poor geological conditions, further subdivision of the cross-section was required. After the roof collapsed, excavation work with a centrally positioned pilot tunnel was stopped. By changing to the top heading method. geological difficulties encountered were controlled. and work was completed. 862252 Limitsquilibrium stability analysis of spiling soil reinforcement in tunneling Bang, S Trans Res Ret N1008, 1985, P58-62
A limit equilibrium analysis for spiling reinforcement in soft ground tunnelling is presented. Radially installed spiles arc inserted along the perimeter of the tunnel opening before excavation, reinforcing both radially and longitudinafly. The system gives temporary support without loosening the weak mass. The analysis takes into account soil properties and the geometry of the tunnel and spiles. It can be used to evaluate the overall stability and to determine design parameters of the system.
Tram Res Ret N1008, 1985, P109-II6
The effects of soil type and density, material properties of the pipe and installation procedures on the soil structure interaction and deformations of buried fibre-reinforced plastic pipes have been examined. Poor haunching, the loose placement of soils in the haunch zones. with no effort to compact to the prescribed density. was the most significant variable in the installation procedure. 862249 Behaviour of braced cut in connection with construction of large underground station Uchida, S; Ito, H; Kaino, T; Tarumi, H Proc international Conference on Case Histories in Geotechnical Engineering, RoUa, Missouri, 6-11 May 1984 VI, P347-354. Pub1 St Louis: Georechnical Engineering, 1984
The behaviour of an underground diaphragm wall in the Ueno Station. Japan,is described. Earth pressure, wall displacements and groundwater levels during construction were monitored. Actual and calculated earth pressure values agreed qualitatively but not quantitatively. Data acquired from this project can be used to improve predictive methods for the behaviour of this type of structure.

Full-face tunnelling machines are becoming more widely used in Norway.

B Tunn Tunnlg VI 7, N7, July 1985, P39-41 Review of papers given at a conference held in Bochum, West Germany, dealing predominantly with small bores of diameters less than Im. discussing the techniques for pipe jacking, the materials used, methods of surveying, economics and the environment. 862254 Soft ground tunnel shields in Japan Yoshikawa, T Tunn Tunnlg VI7, N7. July 1985, P43-47 In Japan, the shield tunnelling method is increasingly being used for projects such as underground railway lines, sewers and other utility networks. A classification of shield machines is described, with the use or non-use of compressed air being the major division into two types, conventional and special. 862255 Settlements due to tunnelling in Hong Kong Cater, R W; Shirlaw, J N Tunn Tunnlg VI7, NIO. Ott 1985, P25-28 Tunnels were driven for the Mass Transit Railway through regions with a variety of geological structures. Initial monitored settlements were less than calculated, suggesting expensive preventative measures could prove unnecessary. The effects of tunnelling method and geology, and the apportionment of settlement between tunnelling and dewatering on decompression for compressed air tunnelling were investigated. Tunnels can and have been driven with little settlement, provided effective support is quickly introduced when cohesionless sands are encountered or there is a high proportion of rock in the face for shield driven tunnels. Advice on prediction of settlements is given.
