The Design of Piled Foundations, Second Edition focuses on the theories which have been advanced to predict the loads which piles will carry, both singly and when used in groups to form a piled foundation. Organized into 12 chapters, this book begins with an explanation of the utilization of piles. Subsequent chapters discuss the types of piles and their construction; pile driving by vibration; the calculation of the ultimate bearing capacity of a pile from soil properties; the settlement of single piles and the choice of a factor of safety; and piles in soft soils. Other chapters describe pile testing; piles in groups with vertical loading; horizontal forces on piles and pile group; and the durability of piles.
