Experimental Study on the Sand of Bandar-e Anzali Using Shaking Table

Abstract

Due to the economic and tourist importance of Bandar-e Anzali coastal zone and also the high seismic risk in this area, this article provides an experimental seismic study using shaking table test on the sandy soil of Bandar-e Anzali. Modeling the laboratory conditions and applying seismic forces were carried out using a transparent tank on a shaking. Additionally, digital instrumentations of horizontal displacement transducers, pore water pressure gauge and data entry device via computer were used. In this study, data collection was conducted by creating saturated samples with relative densities of 20%, 30% and 50% and accelerations of 0.15 g, 0.3 g and 0.53 g and the variation of pore water pressure, horizontal displacement and settlements were measured. The results indicate the high effect of input acceleration on the occurrence of liquefaction and amount of the settlements, especially in low relative density. The effect of higher density on reducing the liquefaction potential and settlement is also significant.
