foundation resting on stratified subsoil. The foundation was loaded with vertical and inclined forces, acting axially and eccentrically. The subsoil ass~ned for the testing consisted of a strong layer overlying a weak one. Three principal problems were analysed based on results obtained from the model tests as follows: the effect of stratified subsoil on the foundation's bearing capacity, the effect of the loading system on the foundation's bearing capacity, and the effect of stratified subsoil on the settlement of the foundation. In the concluding remarks the mechanism of failure for stratified subsoil and practical notes on the soil bearing capacity under the analysed conditions are presented. 782142 D~.'~L~£1NATION OF THE BEARING CAPACITY AND ~ I O N ~SZSTANCE oF Pn~Es BY s o u ~ z m s (IN GEP~AN ) Rollberg, D P~bl Inst Found Eng, Soil Mech# Rock Meah, Waterways ConW~, ~3, 1977, P%3-224 782143 RESULTS OF TESTING DR]V.L~ CAST-IN-SITU PILES IN PLASTIC FROZEN GROUND (IN RUSSIAN) Cherniaev, V I; Mironov, V A Transp Strolt, NIl, NOV 1976, P49-51

Presents a n t ~ e r of case studies including designing for mining subsidence, the founding properties of chalk, foundations on stiff clays and the design and behaviour of deep basement excavations.

1977, V2, P241-246 Reports the use of rockfill t~ provide a foundation w i ~ a high modulus of deformation for the quays and crane tracks at Uddevalla, Sweden. The rockfill layer has a maximum thickness of about 30m ani was compacted by the heavy tamping method usimg 40t and 14t weights. This paper concentrates on the methods used to assess the compaction, concluding that seismic measuremerits in c o , unction with retardation tests of the falling weight proved to be sufficiently accurate tools to replace the expensive plate loading test, and that pressuremeter tests were not so useful.

Concludes that narmslly the bahaviour of piles in cohesive soils is unaffected by the presence of bentor~te. However, evidence from more difficult groumd conditions (such as cohesionless soils under high piezometric presm2res) is limited and no conclusions can be drawn.
