Numerical Modelling of Secant Piles

Abstract

This study presents numerical modeling of a secant pile wall and investigates the lateral displacements, as well as the pressure exerted on the secant pile wall due to the existing soil. The analysis was performed using a finite element method software package, which simulates the behavior of the soil-pile interaction system under various soil conditions. The numerical model considers the geometrical and material properties of the soil, pile, and concrete infill, as well as the effects of water pressure, soil swelling, and ground movement on the stability of the wall. The results of the analysis show that the secant pile wall is capable of resisting the expected lateral and vertical loads, and earth pressures, and the deflection of the wall is within the acceptable limits. Furthermore, the study investigates the effects of different design parameters on the performance of the secant pile wall, including the spacing and diameter of the piles, the thickness and strength of the concrete infill, and the soil properties. The findings of this research provide valuable insights into the behavior and performance of secant pile walls, which can help engineers and contractors to improve the safety and efficiency of deep excavation projects in urban environments.
