237. Puhl Rotterdam: A. A Balkema. 1985 Concerns an earthwork method which utilizes fabrics and ropes for laying sandy soil on reclaimed land where the load bearing capacity is almost zero. There are three principal items for consideration: characteristics of the earthwork procedure: results of surveys conducted on sites with previously completed works: and basic characteristics of the behaviour of the fabrics and the ropes on loading, which were obtained from results of laboratory tests conducted using a one-to-fifty reduced scale model.

Ground freezing 86622 I Mixed fortunes for shaft freezers Tann Tunnig VI8, N5. May 1986. P30-32 The Milwaukee Water Pollution Abatement Project (WPAP) required vertical shafts to be sunk through 52m of soft, waterbearing alluvial soil. then 30m of limestone bedrock. Dewatering was discounted because it would generate excessive settlements, compressed air pressures to control groundwater inflow at depth were too high and caissons were tried unsuccessfully. Ground freezing was adopted and has been used successfully, albeit with many problems.
866218 Strength characteristics of lime-stabilized mine tailings Arioglu, E: Yuksel. A; Agrali, Z Min Sci Technol I"2, N3. April 1986. P161-166 In order to reduce the cost of filling operations at the Uludag Tungsten Mine, Turkey, the utilization of lime in place of cement as a stabilizing agent was investigated. The test program consisted of determination of the strength and deformauon propcrucs, including unconfined compressive strength, tensile strength, cohesion and tangent moduli of elasticity of various tailing~lime ratios for curing times of 7. 14 and 28 days. Results indicate the increase in lime content caused a significant tmprovement in strength with curing time. It is coneluded that the use of lime as a substitute I\~r cement seems possible. Auth.

K Proc Symposium on Recent Developments in Ground Improvement Techniques, Bangkok, 29 Nov-3 Dec 1982 P239254. Publ Rotterdam: A. A. Balkema. 1985 The 'Sheet Method' described is a surface layer treatment for soft ground using flexible sheet materials leg t;abrics) which have no inherent rigidity or a net which has slight rigidity. The effect of the sheet method in laboratory experiments is examined. Two examples of the sheet method, one on the sea bed. the other on land, are given.

Balkema. 1985 Considerable work has been undertaken over the years on ground improvement works by the Department of Highways, Thailand. A summary and brief description of the work is presented. Some early results on the possible use of lime columns in Bangkok clay are also given. Introduction of geotextiles in civil engineering works began in 1978 and since then there has been a growing market in the use of non-woven
866222 Determination of ice forces with centrifuge models Clough. H F; Wurst. H L: Vinson. T S Geotech Test J V9, N2. June 1986. P49-60 A test system and procedure were developed tbr centrifugal modelling of ice forces on offshore structures, The apparatus and instrumentation for measurements of loads, displacements and temperature are described. Ice sheets were formed by prolonged application of wtporised liquid nitrogen. Test results indicate a relationship between thickness, temperature and time. which allows creation of ice sheets of predetermined thickness in the centrifuge. Test results from ice load later~d pile tests compare fiavourably with those from other workers.

Organising Committee, 1986 Reclamation procedures used in Singapore are described. A thorough site investigation was carried out in advance of the projects. Vane shear tests and thin wall piston sampling allowed soils to be tested with minimum disturban~:e, and mechanical properties to be determined. These properties were used in settlement and slope stability calculations for the reclamation and construction of headland rockbunds. Containment dykes were used to reduce the danger of slope failure through rapid drawdown, and the loss of fine material from the fill. Comprehensive instrumentation of the site and strict quality control of the fill material contributed to the successful project.
