ABSTRACT
The lateral bearing capacity of bored piles is determined by horizontal stresses and soil strength. The paper investigates the influence of piling technology and loading history on horizontal stresses, as well as the effect of polymer solution, which has recently been used in piling, on the strength characteristics of the ground. As a result, it is found that the horizontal stresses can vary many times depending on the bored pile technology. The horizontal stresses increase as the pile is loaded. An additional increase in horizontal stresses occurs as a result of the mutual influence of the piles. The application of polymer solution instead of bentonite increases the resistance along the side surface of the ground up to 30%.
