Experimental Study on the Drained Shear Strength of Unsaturated Clayey Sand

A series of tri-axial and direct shear tests have been conducted for the unsaturated clayey sand which was collected from the subgrade in a trial section of the Guangzhou-Foshan Expressway. Drained tri-axial tests were carried out by controlling the matric suction and net room pressure. The direct shear tests were performed by controlling the matric suction and net vertical pressure. Through these tests, the stress-strain relation is obtained together with those deformation and strength parameters. Furthermore, the variations of deformation and strength parameters are explored as the matric suction and net confining pressure vary.
