Pile Groups: Bearing Capacity

This lecture covers the concept of pile groups, including the calculation of isolated piles and the bearing capacity of pile groups in different soil conditions. It discusses the definitions, Whitaker's experiments, and the efficiency coefficient for pile groups. The lecture also explores the behavior of pile groups in clays and sands, emphasizing the differences in load-bearing capacity and rupture mechanisms. Practical formulas and considerations for designing pile groups are presented, along with case studies of large-scale pile group tests in sand. Overall, the lecture provides a comprehensive understanding of the factors influencing the bearing capacity of pile groups in geotechnical engineering.
