Abstract
It has become crucial to study the different pile types in terms of their performance and bearing capacity due to the growing use of different types of piles throughout numerous construction projects. The bearing capacity of piles has been determined for this purpose using various analytical, numerical (finite element and finite difference), and field approaches. To determine pile-bearing capacity, geotechnical engineers and accountants prefer to utilise analytical pile design methods, which take into consideration a variety of methodologies and the soil conditions for each method (such as adhesion, internal friction angle, etc.) Design decisions are made depending on the opinions that are expressed. By comparing the analytical and software results using Plaxis 2D software, using the design results of more than 30 heaps, and analysing prior studies, we attempted to gauge the validity of each of these approaches in this study. For the analyzed piles, the greatest relative error between the theoretical technique and the numerical approach utilised in this study was around 14%; however, this error can be greatly decreased by modifying the meshing and making it finer since the method answers the method. Based on the findings, it was concluded that accurate calculations of the bearing capacity of piles could be made using numerical models and appropriate behavior models for the soil and piles. Therefore, it is somewhat true, rational, and appropriate that numerical models can prevent costly loading tests on piles.
