In this study, consolidated undrained triaxial compression tests on Joomunjin standard sand were performed to investigate the shear behavior of the sand under different confining pressures and relative densities. The following characteristic undrained shear behaviors of the sand were observed from the test results: 1) Decrease of negative pore pressure for loose sand; 2) Increase of negative pore pressure with softening stress-strain relationship for dense sand; 3) Decrease of negative pore pressure with increase of confining pressure.
