摘要

The report describes results of a series of laboratory tests performed to understand better the strength properties of highly plastic clays used in the construction of embankments in Texas. Previous studies showed that such embankments failed by sliding many years (10-30) after construction and that the apparent shear strengths in the field were substantially lower than the long-term shear strengths determined on the basis of laboratory tests on compacted specimens. The report presents the laboratory procedures and results for several series of tests in which specimens of compacted Beaumont clay were subjected to repeated cycles of wetting and drying and then sheared to measure the shear strength parameters in terms of effective stresses. Results of the tests show that repeated wetting and drying can produce a significant reduction in the effective stress cohesion intercept. Factors of safety were calculated using the reduced laboratory strengths for an embankment which had failed.
