CONSOLIDATION OF ALLUVIAL CLAY UNDER REPEATED LOADING.

When repeated loads are applied to a foundation, the deformation of the foundation soil may increase significantly in comparison with the case of static load applications. For this reason an unconventional calculation in the case of repeated loading needs to be made for estimating the deformation of the soil. Among the various types of repeated loads some typical examples are earthquake forces, vehicle loads and oil storage tank loads. Specially-devised consolidation tests under static and repeated loading were performed on remolded saturated cohesive soil samples. As the settlement of the foundation under repeated loading is caused and governed primarily by the magnitude of total load, the loading period, the load increment ratio and the number of load cycles, it is suggested that all of these factors should be considered in predicting the settlement induced by repeated loading.
