dc.description.abstractThe Hetangian Dagorda claystone Formation occupies the core of a diapir outcropping in part of the city of Leiria, exhibiting a complex geological structure. The geological and geotechnical characterization is presented based in field observation and laboratory tests allowing to conclude that the Dagorda clay soils exhibit an unfavourable behaviour for urban occupation, due to the presence of expansive clay minerals. When partially saturated these soils can lead to cracking of walls and floors, or even to endanger the stability of buildings, if they have not been strengthened to resist to expansive soil. The presence of soluble minerals, mainly gypsum and seldom halite, can allow the formation of voids and eventually the deformation or collapse of the ground. Suitable safety procedures, in order to prevent hazards should be used.eng
dc.description.sponsorshipThis work was funded by the Portuguese Government through FCT –Fundação para a Ciência e a Tecnologia under the project PEst-OE/CTE/UI0073/2011 of the Geosciences Center. We would like to thank the Polytechnic Institute of Leiria the conditions for carrying out the laboratory work.
