Abstract
Nowadays, highly efficient construction materials such as bored piles have various benefits for use in civil and foundation engineering. The technology of drilling piles has applications for heavy, concentrated vertical and horizontal loads, on building sites with complicated geological and engineering conditions, in densely populated urban areas, and close to existing buildings and structures where deformations may occur from hammering or vibration loading effects. The study is devoted to the investigation of the properties and application of bored piles as a foundation and the significance of their use in the current civil engineering conditions, as well as conducting a comparative analysis of the dependence of the bearing capacity of a bored pile on the change in its diameter and depth of laying.
