Liquefaction is one of the significant hazards associated with earthquakes. It was previously believed to occur mostly in clean sands; however, recent research has shown that liquefaction can occur in specific conditions in sands mixed with fine or coarse particles. Numerous studies have been conducted on clean sand, while limited research has focused on sands mixed with silt. Nevertheless, the liquefaction resistance of sands mixed with coarse particles has received less attention in previous studies. This research investigates the liquefaction potential of sand mixed with gravel using cyclic triaxial testing. The experiments were performed on Ottawa sand mixed with various percentages of gravel. The study evaluates the influence of parameters such as relative density and gravel percentage on the liquefaction resistance of the mixed soil. The results indicate that the gravel percentage and relative density of the samples significantly affect the liquefaction potential.
