     shore sands are considered to be susceptible to liquefaction due to their fine and uniform grading. one of the most important factors affecting the liquefaction strength of sands is the cyclic stress ratio induced during seismic loading. a series of monotonic and cyclic triaxial tests were carried out on reconstituted samples of anzali shore sand in order to study the effect of cyclic stress ratio on the process of pore water pressure generation until occurrence of liquefaction. the results were interpreted through critical state soil mechanics framework. it was found that the cyclic response of anzali shore sand could be simplified as an exponential function of cyclic stress ratio in any given initial state.
