Abstract

The article discusses and justifies the cases of horizontal movement of the top of the piles in the case of digging a pit of great depth. A statistical analysis of the results of executive documentation for completed pile fields at three construction sites in St. Petersburg was carried out, which made it possible to prove the causes of excess movements of the pile heads. A technique for assessing deformations depending on the depth of excavation of the pit and the characteristics of the soil base is proposed. The decrease in the modulus of subgrade reaction for calculating piles in the conditions of softened soils near the pile space is proved.
