rigid disk resting on a nonlinear inelastic half space with slip permitted along the interface and on a linear elastic half space without slip. Experimental and nonlinear numnerical results were found to agree well. It was concluded that accurate Irediction of the dynamic response of soil-foundation systems where large shearing strains develop, requires consideration of the nonlinear elasticity of the soil.

Solutions are ~ o p o s e d to some of the geotechnical l~obl~ns anticipated due to the presence of gypsum. The solubility, stress-strain-time behaviour, effect of environmental conditions on the mechanical l~operties of gypsum and the effect of gypsum on fourdation concrete are studied. Recommendations for the founiation design of the Complex include the use of a sulphate resistant cement, and a maximum temperature of 80 deg C to be transmitted by the structure to the ground. 834235 SOFT ZONES IN THE GLACIAL TILL IN E~4ONTON. TECHNICAL NOTE Thomson, S; Martin, R L; Eisenstein, Z Can Geotech J, VIg, }~2, May 1982, P17~-180 Glacial till in the Edmonton area, Cs2mda, has previously been regarded as an entirely satisfactory foundation material. However, site investigations for a tower block have revealed the l~esence of anomalously soft zones. It is concluded that earlier experience with dense tills had led to an aver-confident approach to soil investigation. 834236 ANALYSIS OF THE STATIC LOADING TEST OF A PILE WITH THE H~F~P OF ~N INTERACTIVE DISI~AY: THE 'PELAGI ~ P R O G R ~ Bustamante, ~; Gianeselli, L; M~reau, M Bull Liaison Lab Ponts Chaussees, Nl21, Sept-Oct 1982, P93-102 83~237 EXPERI?CENTAL S_~X]DY OF A PILE SUBJEC~'Eu TO LATERAL soIz E R E S ~

BigOt, G; Bourges, F; Frank, R Rev Fr Geotech, N!8, Feb 1982, P29-47 A full sc~le test of an isolated pile at the foot of an embankment built on ecml~essible soils was performed. A comparison of experimental results with various theoretical results using recent design recommendations is ~esented.

83h-238 UNDERPINNINO (IN FRENC'T~I) Hurtsdo, J Rev Fr Geotech, NIS, Feb 1982, 1:59-66 Two exomples of repairs to buildings damaged by earth movements are described. In Grenoble, deep excavation for water works has caused weakening of the pile foundations of a building. New piles Jacked down by 0.8m elerents have been used. In Menton, the collapse of a retaining wall against two buildings due to heavy rain caused one building to collapse. The other has been saved by construction of a new retaining structure behind the collapsed wall.

A simple method is described far quick estimation of pile settlement using cone resistance measured by a cone penetrometer test (CPT). A method, applicable to heterogeneous soils, for the estimation of the elastic and elastoplastic zones of the load settlement curve of a pile is smggested. 834241 BEARING CAPACITY OF FOOTINGS IN GRANULAR SLOPES Bauer, G E; Shields, D H; Scott, J D Proc 10th Internatior~l Conference on Soil Mechanics amd Foundation Engi:~erir~, Stockholm, 15-19 June 1981 , V2, P33-36. Publ Rotterdam: A. A. Balkema, 1981 Results of controlled experiments to measure the ultimate bearing capacity of footings at various locations within a granular slope are l~esented. In one series of tests, two sizes of footings, 0.3 and 0.6m wide, were used to study the scale effects, and in another series of tests loads were applied in both vertical and inclined directions.

The model includes the effect of the s t r ~ u r e rigidity, a linear rheologic model of the soil, amd the non-homogeneity of the soil ~o;erties (by Usimg stochastic parameters). The analysis allows the reliability of the structure to be evaluated. 8342~/~ PERFORMANCE OF FOUNDATIONS FOR MASTS ON SAND Blmnel, W; Lackner, F Proc 10th International Conference on Soil Mechanics ard Foumdation Emglnmerimg, Stockholm, 15-19 June 1981, V2, ~9-52.
