Contribuição ao estudo da resistência não-drenada e secagem dos solos compactados em laboratório das áreas de empréstimo da barragem Palmar

The undrained shear strength of compated, unsaturated soils as determined triaxial tests with the relationship K=σ3/ σ1 = constant lead to two realationships: the first related with the parameter (e√S)o at the beginning of the test and the second with the sarne parameter (e√S)£ at failure. The soils in this dissertation had optimum water contents (as defined hy the Proctor Compaction Test) essentially egual to their Plastic Limits. These, compacted at different water contents with the same compacting energy (Proctor Test), when air-dried establish relationships between the parameter (e√S) and water content. That depend upon the initial compacted condition. The laboratory test results allows us to forecast the order of magnitude of the influence of a previous drying up to the undrained shear strength. These forecasts assume, as a working hypothesis, that the relationship (e√S)o vs. undrained shear strength is independent of the drying process.
