Pages: 9-20
Abstract text:
Expansive/active soils that consist of reactive minerals (which present unstable networks and thus tend to modify their volume by water adsorption and cationic exchange) raise a major challenge to geotechnical engineers being also considered geological hazards. Studying the potential volume changes of a soil becomes compulsory (because of the degradations that might appear following heaving and settlement) at the outset of future construction projects, especially the low weighted ones and positioned close to the surface and thus subjected to a greater extent of water content variations. This study investigates the swelling and compressible behavior of undisturbed samples of Bahlui clay using a direct method. Indirect methods of estimating the swelling potential are considered as well.
Key Words:
active soil; Bahlui clay; swelling pressure; compressibility.
