Abstract
In order to examine the influence of viod ratio, and grain size distribution to the unsaturated shear strength of sandy soil. Conventional triaxial compression tests were performed for saturated and unsaturated sandy soil specimens with different initial void ratio, 50 percent diameter, and uniformity coefficient, Based on the test results, the in fluence of these properties to the shear strength increment to the increase of suction were made clear as follows. With the increase of initial void ratio and 50 percent diameter, the shear strength increment becomes smaller, while the shear strength increment becomes larger with the increase of uniformity coefficient which gives largest influence to the shear strength.
