This lecture covers the calculation of the axial bearing capacity of isolated piles, including the mechanisms of failure, laboratory and in situ testing, estimation by driving formulas, and safety verifications. It also discusses the different models for soil rupture around piles, the influence of pile length on point resistance, and the estimation of pile capacity according to various models. The lecture further explores factors influencing the bearing capacity of piles, such as negative friction, soil resistance, and implementation methods. It concludes with the calculation of bearing capacity based on different methods and the analysis of settlement phenomena.
