Abstract:

Soil tests were conducted to provide information on the influence of degree of saturation on high-pressure stress-strain relations of undisturbed and remolded soils and to provide input data for computer codes concerning the relation between stress and strain invariants at high pressures. The test results presented herein show that large strains do not develop at high pressures in fine-grained soils such as silt and clay. The test program consisted of 12 one-dimensional tests on 4 specimens each of undisturbed and remolded silty clay, and 4 specimens of remolded silty clay, and 4 specimens of remolded sandy silt. In all tests the radial strain was essentially zero. Axial and radial stresses and axial strain were measured. The tests were carried to an axial stress of 20,000 psi unless soil extrusion occurred at a lower stress.
