Effect of Contact Pressure on the Lateral Capacity of Piles
Abstract
This study aims to determine how to contact pressure affects pile capacity. First, a single pile model was subjected to a total of six tests, five conducted under varying surface loads and one conducted on a single pile raft. Plaxis- 3D was utilized in the second step of numerical modelling to imitate experimental activity. The galvanized iron pipe was used as a model pipe, and for confining pressure, a rectangular plate made of aluminum had a slot in the center for placing a pile. For numerical study in Plaxis 3-D pile was used as a model pile surrounding the soil to find the relative displacement between the piles and surrounding the soil. In the proposed research work, the axial and lateral capacity of the pile increases due to the contact pressure of the soil. As a result of the interaction between the pile and the raft, when the results were compared, the pile tightly connected to the raft took less axial force than the other pile that was not. Similar outcomes emerged from the trials when they were conducted in Plaxis 3-D.
