Shear zones in tertiary clays, abstract in slips, shrinks and swells: Clay minerals & geotechnics

No full textThis paper examines the literature to find a realistic forecast of sea-level change during the coming millennium. Climate change induced by greenhouse gas emissions is put into the perspective of changes in CO2 concentrations during geological time. Global dimming is currently acting as a negative feedback but in time this effect should reduce and in conjunction with a likely high emissions scenario, temperatures will rise significantly. The resulting sea-level changes during the next millennium will have very serious implication
The Bargate Centre, Southampton: the engineering geological and geohydrological aspects of the excavation for basement construction
No full textThe Bargate Centre is a large, four-storey shopping arcade constructed during 1986–1990 within the medieval town walls of Southampton. It incorporates a basement requiring construction to between 6–7 m below ground level through fill, brickearth, and water-bearing river terrace gravels overlying mainly laminated clays of the Bracklesham Group. The case record is of particular interest in that the excavation cut-off wall acted as a barrier to the original (that is, pre-excavation) groundwater seepage in the terrace gravels. Observations of the piezometric levels before and after construction confirm ponding on the upstream side of the basement. However, it appears that the pre-construction seepage pattern on the downstream side was modified by the medieval double moats which are known, at least in part, to have been excavated into the terrace gravels
