摘要：

The method developed by Casagrande to determine a preconsolidation stress from consolidation test results is widely used when a stress threshold value is to be determined from the results of a uniaxial compression test on unsaturated, structured, soil. This paper describes how this graphical method was transformed into a computer method using Lotus 123. Application to samples from a tractor rut showed ageing effects and effect of speed in the uniaxial compression tests.
