Abstract
In civil engineering projects, construction on saturated compressible soft soils such as clay and silt is unavoidable. the great problem facing construction on this type of soil is the consoildation settlement, which is time dependent phenomena. Chages in the soil properties and time dependent loading such as cyclic loading during the consolidation process would affect the rate and amount of the settlement at any particular time.
Cyclic loading are often applied to clay layers under structures subject to loading and unloading circumstances such as ground water tanks. one of the problems that may be occur is the time-dependent loading and settlement with considering full compatibility between the structure and the soil.
