Performance improvement of vertical anchor plates in sandy soil by using geogrid reinforcement

Abstract

The stabilization of an anchoring system plays a significant role in geotechnical engineering structures. To develop a clear understanding of the vertical plate anchors behavior due to geogrid reinforced soil under various pullout load inclination ranging from (0, 25, 45, 60, and 90) degrees in Cohesionless soil, a series of total (34) tests were carried out. The soil has been investigated by using small-scale model tests. Geogrid with different width and heights placed (vertically or horizontally in front of the vertical anchor plate at different locations were used to reinforce a soil mass in front of square anchor plates. The studied parameters include reinforced soil mass width, soil mass height, the location of geogrid-reinforced soil mass, effect of water content increase, and the inclination angle of pullout load. The test results indicate that Geogrid reinforced mass in front of a vertical anchor plate significantly increases the stiffness of the soil and increases the pullout resistance of shallow anchor plates. According to test outcomes, critical situations also were stated and discussed.
