Abstract: Saturated sands subjected to earthquake loadings can develop two different phenomena, i.e., liquefaction and cyclic mobility. Liquefaction can develop only in loose sands and its mechanism is related to the critical state of the sand. Cyclic mobility can develop in any sand. The results of the cyclic triaxial tests used to study cyclic mobility are conservative for medium dense and dense sands, because of redistribution of water content in the specimens during the tests, application of axial extension loads, and loosening of the sand during sampling. To obtain an estimate of the conservatism of the cyclic triaxial tests a comparison was made of the observed field behavior of saturated sands during earthquakes and of the results of cyclic triaxial tests on undisturbed samples.
