The anchors are tensile members that can withstand external tensile forces by connecting to the structure and placing them at a suitable depth in the ground. Different types of anchors have been introduced for stabilization in marine and land areas. This study deals with the experimental investigation of a new type of plate mechanical anchor with the ability to open the plates in the soil. The effect of different factors such as the effect of dividing the surface in plates, pulling out speed, distance between plates, and soil density on the final pulling out capacity of expanded plate anchors buried in sand bed has been investigated using physical modeling in this study. Particle Image Velocimetry was used to investigate the formation of rupture wedges and the mobilization of the soil volume placed on the plates. The results showed that by keeping the area of the plates constant and only by changing the distribution of the area from the case of two-plate an-chors with equal area to two-plate anchors with more area distribution on the lower plate, the pull-out capacity of the anchor has increased 2-3 times. Also, the investigation of the performance of the expandable double-plate anchor under different pull-out velocities showed that the pull-out velocity of the anchors in sandy soils has little effect on the pull-out capacity.
