DESCRIPTION:Prof. B. Caicedo\, Universidad de Los Andes\, invited professo
 r at LMS\nThe increasing interest in the study of the THM response of soil
 s due to hydrological variations has heightened the need for improvements 
 in the basic understanding of heat and mass transport taking place at the 
 soil-atmosphere interface. Numerous hydrological parameters affect this th
 ermo-hydro mechanical process: solar radiation\, air temperature\, atmosph
 eric pressure\, wind velocity\, rain intensity and hygrometry. Only few re
 sults of soil-atmosphere interaction based on field tests are available to
  calibrate numerical models since these studies require measurements over 
 long periods of time\, in particular when attention focuses on the cyclic 
 behavior during wetting and drying. On the other hand\, due to extreme cli
 mate conditions large cracks in soil deposits have been identified in many
  locations in different parts of the world. Various studies have examined 
 processes of crack formation and interactions with atmospheric conditions\
 , but the effects of cracking on bearing capacity has received little atte
 ntion.\nThis seminar will expose some studies in a climatic chamber that a
 llows understanding the effect of each environmental variable on the soil 
 atmosphere interaction. Furthermore\, results of centrifuge tests to simul
 ate the influence of cracks and desiccation on the bearing capacity of sha
 llow circular foundations will be presented.
