OBSERVED TIME DEPENDENT BEHAVIOR OF SOILS

Abstract eng:
Time-dependent behavior of soils has been investigated extensively through one-dimensional and triaxial test conditions. The phenomena associated with time effects in soils are creep, relaxation, strain rate effects and accumulated effects. Most of the observations presented in the literature have focused on the determination of time-dependent behavior of clayey soils, whereas the reported experimental studies of granular materials are few. Nevertheless, time effects in granular materials such as sand are not negligible. This paper presents a concise review of results from triaxial tests on sand and clay. The purpose of the tests was to examine strain rate effects and accumulated effects. From the tests it can be concluded that clay to some extent shows isotach behavior whereas sand exhibits non-isotach behavior. This fact has major importance in connection with modeling of sand and clayey soils.
