This paper presents the results of the triaxial tests performed on medium sand and sandy clay samples. The shear strength and deformation characteristics from consolidated drained (CD) tests performed in a controlled saturation state were determined. The study was conducted in a modern apparatus for triaxial testing of unsaturated samples. Test specimens with a diameter of 70 mm and height of 140...
For mastering the strength and deformation properties of sand under high pressure, DRS-1 high pressure direct shear test system was used in shear test of Fujian standard sand under 12 to 15 MPa. Through analysis of the test results, we obtained that shear properties of standard sand under high pressure show strain hardening, it is consistent with Duncan-Chang hyperbolic model. There is a proportional...
