ABSTRACT: In this paper, the effect of salts on the determination of the water content and Atterberg limits of sabkha soils has been studied. The tests were performed using distilled water, natural sabkha brine and saline solutions with different salt concentrations. The results indicate that the liquid and plastic limits decrease with pore fluid salinity when the conventional water content procedure is used, but increase when the fluid content method is used. Also, the liquid and plastic limits measured using percussion-cup test and rolling test method are compared to those measured using the fall cone test method.
RÉSUMÉ: Dans cet article, nous étudions l™effet des sels sur la détermination de la teneur en eau et des limites d™Atterberg des sols d™une sabkha. Les essais sont effectués en utilisant de l™eau distillée, de la saumure d™une sabkha et des saumures préparées au laboratoire avec différentes concentrations en sel. Les résultats montrent que les limites de liquidité et de plasticité diminuent avec l™augmentation de la salinité du liquide lorsque la méthode conventionnelle de mesure de la teneur en eau est utilisée et augmentent lorsque la méthode de teneur en fluide est utilisée. Aussi, les limites de liquidité et de plasticité mesurée à l™aide de l™appareil de Casagrande et la méthode du rouleau sont comparées avec ceux mesurées en utilisant le pénétromètre à cône.
