Volumetric and elastic behavior Multi-dimensional swelling behavior of Al-Qatif expansive soils

Chen & Ng 2005) in attempt to replicate field conditions. Dakshanamurty (1979) showed that the volumetric strain depends on the mean stress. Tisot & Aboushook (1983) mentioned that the prediction of heave may be improved by applying anisotropic stress during triaxial testing. However, the test duration makes the triaxial testing useless.
