Effect of Sand Relative Density on Response of a Laterally Loaded Pile and Sand Deformation
Two scale-model tests were separately conducted in standard Toyoura sand with relative density of 50% and 80%. The effect of sand relative density on pile-soil interaction was investigated through the response of a laterally loaded pile and the sand movement around the pile. At a displacement of 3.6...
