Experimental Investigation of the Behavior of Executed Pile Models with Applied Torque in Frustum Confining Vessels
A deep foundation is used to transfer the load of tall and large structures to the underlying soil layers with a sufficient strength. Over the last few decades, a new type of piles has been executed in developed countries using torque with the development of hydraulic devices that can create high torques. Due to the emergence of these deep foundations, the scope of studies in this regard are limited. Thus, studying the behavior of these foundations can increase the breadth of their application in other countries while creating a better understanding of their behavior. In the present research, some models of this type of pile have been created and studied using laboratory equipment and static loading. Execution of drilled displacement and helical piles in the FCV-AUT device as well as running static compression and tension load tests were done according to ASTM D1143 and ASTM D3689 standards. Experiments on the executions have been studied in two modes of density: relative density of 20% to 25% and of 45% to 50%. Accordingly, drilled displacement piles show good performance in terms of compression and tension bearing capacity compared to other piles, while the required installation torque for this pile shows higher values.
