Naturally coarse-grained soils are widely present in many parts of the world such as Tehran, the capital city of Iran which is located in a seismic area. In order to understand the dynamic behavior of this soil, a series of undrained cyclic triaxial tests were performed on reconstituted samples. In this paper, cyclic strength of Tehran soil is evaluated considering the effect of membrane compliance on excess pore water pressure. The test results indicate that in general, by increase in cyclic deviatoric stress amplitude or cyclic stress ratio, the required number of cycles to failure decreases. Also, the maximum excess pore water pressure ratio (ru) approaches to one at failure which can be considered as the initial liquefaction in Tehran alluvium. The medium to high relative density of Tehran soil results in cyclic mobility and limited shear strains as the number of stress cycles goes beyond initial liquefaction no flow liquefaction is observed during the conducted tests.
