3D Numerical Modeling of a Single Pipe Pile Under Axial Compression Embedded in Organic Soil

Abstract

The objective of this paper is to numerically study the behavior pipe pile under axial compression embedded in organic soil has been numerically predicted. The pipe pile used in the study has been produced by steel and it has outer and inner diameters of 20 mm and 15 mm, respectively. The pile embedded in organic soil, which has the pile length ratios of 10, 20 and 30 (L/D), has been exposed to the axial load for different diameter ratios (d/D = 0, 0.25, 0.50 and 0.75). Numerical analyses have been performed by using Plaxis 3D computer program which is based on finite element method. The capability of the numerical analysis in the prediction of the load capacity of pipe pile has been studied. It has been understood that the results obtained from numerical analysis and experiment are in a good agreement, and then it has been observed in the parametric study that the load capacity of single pipe pile increases with the increase of the pile length and the wall thickness.

Improving bearing capacity of weak soils: A review

“…According to Sharma and Sanadhya (2020) [23] , increasing the stiffness of the granular pile and bearing stratum causes decreases top displacement and settlement ratio as well as increase in normalised shear stresses near the raft and percentage load transfer to the raft. 2020) [24] discovered that the ultimate load of a pile increases with increasing L/D and decreases with increasing d/D, where L, d and D are pile's length, internal diameter and external diameters respectively. Similarly, Majeed and Haider (2018) [25] identified numerical analysis as the most cost-effective method of estimating pile potential because both field and numerical results agreed so well.…”

Numerical analysis of pile group, piled raft, and footing using finite element software PLAXIS 2D and GEO5

“…The optimal pile arrangement can be chosen to minimize differential settlement by taking into account loading intensity and serviceability limit factors 6 .To ensure the long-term functionality of organic soils in construction projects, various soil modification techniques are employed, including methods like cutting and replacing, displacement, or pre-compression 7 . Pile foundations are also employed to address issues about the insufficient strength and excessive settling of organic soil 8 . When shallow footings cannot accommodate these loads, PRFs are typically used as a substitute 1 .…”

“…Piled raft foundations have gained significant popularity in recent years due to their ability to combine the bearing capacities of piles and rafts. Extensive research has been undertaken to ensure the reliability and cost-effectiveness of designing such foundations through rigorous analytical, numerical, and experimental studies 8 , 15 . Various foundations are considered depending on the type of construction.…”

Multi-objective design and optimization of squeezed branch pile based on orthogonal test

“…In order to make pile foundations provide higher bearing capacity, pile lateral friction resistance and pile bottom end bearing capacity are the two main areas of research conducted by scholars. In recent years, a large number of scholars have studied various aspects of different pile foundations in different soil conditions [1][2][3][4][5] , of which experimental studies and numerical tests are the main ones, and Ateş, B., Şadoğlu, E. also studied group efficiency with pile groups as the main research object 6 .Traditional foundation treatment methods (such as cast-in-place piles, steel pipe piles, etc.) have problems such as restricted application, difficult construction and high cost.…”
