78~197 HORIZONTALLY LOADED VERTICAL P L ~ E ANCHORS IN SAND. TECHNICAL NOTE Akimmmsuru, J 0 J Geotech E r ~ Dlv ASCE, V104, NGT2, Feb
1978, P283-286 Reports lab tests ahowlmg that at a depth of 6.5 times the anchcm height the behavlour of the anchor chamges fr~n shallow to deep, and that the pullout capacit~ of an anchor is influenced by its shape and size. 784198 EVALUATION OF THE TIE-BACK ANCHOR RESPONSE Kay, J N; Qamar, M I J Geo~ Emgng Div ASCE, Vl04, NGT1, Jan
1978, P77-89 Detailed amalysis of the load-deflection response of cylindrical anchors is made by consid~ation of 4 components, namely free anchor tendon extension, soil deformation, anchor extension and steel-concrete bond slip. Predictions based on the method are applied to field tests and the results are discussed. The proced~e also provides for interpretation of the anchor load test as a field test for measurement cf soil modulus.

Freezing 784206 FREEZE IT Civ E~gng, London, Dec 1977, P53-55 Describes the advantages and disadvantages freezing to improve soil strength or ground conhrol, or both. The process Is applicable a wide range of soil types, from cl8~s to c gravels. Methods using brine and liquid nit are both described.

Soil stabilisation 784199 REALLY POLU~DING IT DOWN Civ Emgng, London, Dec 1977, P41-43 Briefly reviews the technique of dymamic consolidation in which a 8-40t weight is dropped from a height of between 5 and 30m. Bearing capacities may be increased by up to 400 per cent. 784200 TREATMENT OF ALLUVIAL SAND WITH POZZOLAN-LIME BINDER (IN FRENCH) Geoffray, J M; Valladeau, R Bull Liaison Lab Ponts Chaussees, N93, JanFeb 1978, I~6-91 The binder gives mixtures which harden gradus3_ly with i~nediate bearing capacity. Production and application are straightforward, though cos~ is the main problem. 784201 SOIL STABILIZATION WITH LIME IN ROAD AND AIRPORT CONSTRUCTION (IN RUSSIAN) Levchanovskli, G N; Markov, L A; Popardopoulo, G A MOscow: Transport, 1977, 149P 7811-202 GEOPHYSICAL MEFHODS OF QUALITY CONTROL FOR LOOSE SOIL STABILIZATION (IN RUSSIAN) Bochko, E A; Dubrovln, V S Moscow: Nedra, 1976, 87P 784203 USE OF OIL-BASE DRILLING MUD IN FREVENfING LANDSLIDES AND CAVE-INS (IN RUSSIAN) Avetisian, N G; Kasl~mrakii, B V; Koshelev, N N Burenie, N2, 1977, P36-38
Site Investigation and Field Observation 784208 PLATFORM SITE INVESTIGATION Sullivan, R Civ Engng, London, Feb 1978, P26-33,45 Outlines the stages in the investigation of potez~clal off-shore site with particular en on sampling and in situ testing techniques such as percussion sampling and the cone p~ rometer. In situ tests are considered to be pl~-mm-~tary to detailed on shore laboratory testing of dynamic and other properties of soll samples. 784209 THERMOELASTIC STRAINS AND TILTS REVISITED Harrison, J C; Herbst, K Geophys Res Left, V4, Nll, Nov 1977, P535 Coupling between the thermal boundary layer surface topography is an importsr~t source c thermoelastie tilts and strains. Simple for are given to compute ~hese effects on unifc slopes. It is shc~n that a reduction in the coupling effect can be obtained by burying struments at a suitable depth.
