Abstract :
    Due to the increasing use of various types of piles in various construction projects, it has become important to examine the types of piles in terms of their performance and bearing capacity. For this purpose, various analytical, numerical (finite element and finite difference) and field methods have been presented and used to calculate the bearing capacity of piles. Geotechnical engineers and accountants prefer to use pile design analytical methods to calculate pile bearing capacity, which includes several methods in each of these methods soil parameters (such as adhesion, internal friction angle, etc.) Opinions are placed and design is done based on them. In this study, in addition to reviewing previous researches, by using the design results of more than 30 piles and by comparing the analytical and software results using Plaxis2d software, we tried to measure the validity of each of these methods. Based on the obtained results, it was concluded that by using numerical models and choosing suitable behavior models for soil and piles, the bearing capacity of piles can be calculated with proper accuracy. Therefore, the fact that numerical models can prevent expensive loading tests on piles is true to a certain extent and is logical and applicable.
