Determining shear strength of a unsaturated soil by the constant water content triaxial tests

Abstract

     Many geotechnical problems for stability and strength are related to the shear strength of a soil. In general, most of soils in real constructions are the saturated/unsaturated soil system. Therefore, it is necessary to simulate this condition in a constant water content triaxial test (CW) to determine shear strength of the soil. This research presents the method of determining shear strength of the unsaturated soil by the constant water content triaxial shearing tests (CW). The equipment for this research is the modified triaxial apparatus in the Geotechnical laboratory in Hanoi Water Resources University.
