Abstract

Pile foundations are a commonly used option for constructing buildings, bridges, embankments, and other structures. However, there are several methods available for determining the load-carrying capacity of piles, such as Meyerhof's method, Terzaghi, Peck and Mesri (1996), and the Japanese Institute of Architecture. These methods provide predictions of pile load-capacity but may differ from the results of the pile static test conducted in the field. However, the calculation methods for determining the bearing capacity of piles take into account the frictional resistance that occurs along the entire length of the pile. However, the frictional resistance along the pile body is affected by the displacement of the pile as it slides into the soil, and the displacement of the soil around the pile tip also affects the frictional resistance near the pile tip. Using numerical methods (specifically Plaxis 3D), the research team simulated and investigated the displacement of soil around pile tips of varying diameters in sandy soil located in Ho Chi Minh City. This study revealed that the frictional resistance near the pile tip decreased at a position equal to 0.865 times the pile diameter.
