Soil-environment interactions in geotechnical engineering
Professor Antonio Gens
In the lecture, a number of developments incorporating the effects of new phenomena and new variables on the behaviour of soils will be described and discussed. Recent developments in Unsaturated Soil Mechanics will be reviewed first. It will be shown that they provide a consistent framework for understanding the engineering behaviour of unsaturated soils and the effects of suction and moisture changes. Building on those developments, soil behaviour is further explored by considering the effect of high and low temperatures as well as of chemical variables. The resulting generalised view of soil behaviour is then applied in the analysis of field situations.
The lecture will present documented case histories that demonstrate the relevance and implications of the developments described for geotechnical engineering practice.
