Abstract:
This paper deals with the laboratory investigation on behavior and pullout force resistance of the bearing reinforcement stabilized on compacted sandy soil at the optimum point of Standard Proctor energy. It was found that the bearing force is fully developed at the bearing reinforcement movement of 65% of the height of the bearing bar and the appropriate spacing and length of the bearing bar is 45 and 15 centimeters, respectively. At any vertical normal pressure, the maximum pullout force is increased proportionally with the number and length of the bearing bar, and at any spacing of the bearing bar, the maximum pullout force is increased proportionally with the vertical normal pressure. In addition, the model for the maximum pullout force of the bearing reinforcement stabilized on compacted sandy soil at the bearing reinforcement movement of 25 millimeters, on the optimum of Standard Proctor energy was proposed. It was verified by using the test results compiled from crushed rock. The predicted and the observed values are in good agreement within acceptable engineering error
