Abstract

This paper highlights the key features of triaxial testing of unsaturated soils. The modifications to a conventional triaxial apparatus and the test procedures for various unsaturated soil triaxial tests are described. Test results for an undisturbed residual soil tested under consolidated undrained (CU) and constant water content (CW) conditions at three different strain rates are presented. The test results showed that φ^b is not a constant, but decreases as matric suction is increased. The shear strength envelopes obtained from CU and CW tests at the three different strain rates are similar.
