The research of influence of piles with cross section on the pile’s load capacity is published in this article. Special attention to driven piles was paid, because they are very popular in building area. There are five cross-sectional shapes: round, square, cruciform, T-bar, I-beam.As а soil selected a single layer from the fine-grained sandy soil.The calculation of the bearing capacity of piles was conducted with the data cross-sectional shapes. As a result, authors explored that constituent which depends on exterior perimeter of pile’s cross section is very important.
