Résumé
Expansive clay soil was encountered in different areas of Saudi Arabia. This study presents the locations of this type of soil in the Eastern Province of Saudi Arabia and its characteristics. The study showed that Al-Qatif and the villages around it, as well as Al-Hofuf and the villages around it are rich in expansive soils. Climate and geology of the area have a big influence on the formation and behavior of expansive soils. Clays in Al-Qatif area are highly plastic, possess very high swelling potential and rich in smectite, illite, dolomite and palygorskite. Al-Hasa clays are plastic, possess moderate to high swelling potential and rich in calcite, illite, palygorskite and kaolinite. A strong correlation between swelling potential and the plasticity of the clay was found and an empirical equation was developed to present this correlation. Finally, the study showed that an increase in surcharge load decreases the magnitude of percentage of swell while the swelling pressure remains almost constant.
