摘要：

This study aims to understand the shear strength of unsaturated Malaysian granitic residual soil. The soil was obtained from Kuala Klawang, Negeri Sembilan, Malaysia. A pressure plate was used for obtaining soil-water characteristic curves under zero net confining pressure. Multistage consolidated drained triaxial tests were carried out on both saturated and unsaturated compacted specimens at a constant strain rate. The experimental data of the saturated and unsaturated shear strength of the soil were fitted with a comprehensive constitutive shear strength model that represents both linear and nonlinear shear strength behaviors, with respect to suction and net stress or effective stress for unsaturated and saturated conditions, respectively.
