PRESSURE-TIME RELATIONSHIP IN FROZEN COHESIVE SOILS UNDER LATERAL PRESSURE

The reduction in stress with time of a frozen clay layer subjected to lateral pressure at a constant temperature was studied to investigate its general behavior and to correlate this behavior with some relevant parameters. Frozen specimens of two different cohesive soils were tested at various constant temperatures under selected initial pressures. The experimental results were plotted in the form of pressure versus time and reduction in stress versus time curves, and the time-dependent behaviour of the clay-ice-water system under an applied load compared with the behavior of a previously investigated sand-ice system. A general equation for the prediction of the lateral pressure retained by the frozen clay layer at any time after application of a known initial pressure was derived empirically. /Author/
