: Strong earthquakes cause liquefaction, which causes significant damage to buildings and infrastructure. The purpose of this study is to investigate the effects of relative density on the liquefaction behaviour of sand using cyclic triaxial testing. In order to recreate essentially undrained field circumstances during an earthquake or other cyclical load for untreated sand specimens, cyclical triaxial strength tests are carried out in an undrained environment. A measure of liquefaction is identified by how many stress cycles are required to reach a limiting strain or a 100% pore pressure. The results shows that as the relative density increases from 10% to 30%, the liquefaction resistance developed from 0 % to 7% approximately. CRR value changes means it's also increase by 0.026 to 0.143 at relative density changes from 10 to 30%. It is concluded that as increase of relative density of sand liquefaction resistance of sand also increases.
