This research introduces an alternative recent technique, bladed pile anchor, which aims to increase the surface area under the soil during uplift. This provides more shear resistance acting along the failure surface and increases the dead weight of the surrounding sand within the failure zone to resist the uplift force. As a result, the uplift capacities are increased. In this experimental study, the effect of many parameters, such as blade length ratio, blade width ratio, and sand relative density, on the ultimate uplift capacity of bladed pile anchors is investigated. The uplift capacities of bladed pile anchors embedded in sand increase with the increase of the blade surface area by increasing the blade length ratio and the blade width ratio. At blade length ratio of 3 and blade width ratio of π/2, the percentage increase in the uplift capacity reaches (275%, 233%, and 230%) at relative densities of (30%, 50%, and 80%), respectively, compared with regular pile. The existence of blades created an ideal anchorage system due to the increased surface area beneath the soil, resulting in increased uplift capacity. This pile modification is valid and suitable for marine structures, and it is easy to install for this application.
