Abstract
The influence of soil reinforcement on the pullout performance of single pile embedded in reinforced and non-reinforced cohesionless soil is investigated. Laboratory experiments were conducted utilizing steel circular pile with lumped surface condition along with a specific soil reinforcement type of (TX150). Several configurations of soil reinforcement were studied by varying the reinforcement layers embedded depth, the reinforcement layers width, and the reinforcement horizontal beginning distance from the pile surface.
The test findings show an important relationship between the pile pullout capacity and the embedded depth of the reinforcement layers, indicating an increase in pile pullout capacity up to two times the pile diameter. Furthermore, the results exhibit that the pullout capacity of the pile increases with the increase of the reinforcement width up to nine times the pile diameter. Also, the results show that there is a significant decrease in the pile pullout capacity with the increase of the reinforcement horizontal beginning distance from the pile surface. These results provide important insights into improving single pile performance under pullout loads using soil reinforcement techniques.
