ABSTRACT
This chapter introduces the commonly used types of deep foundations from the perspectives of material, geometry, load transfer mechanism, construction-induced ground displacement, and construction method. It describes the methods for static analysis of axially loaded deep foundations and factors to be considered in the analysis. The chapter also describes the background and techniques involved in the analysis of laterally loaded piles. It discusses the effects of installing a group of piles in close proximity in axial and lateral loading conditions. The chapter explores the phenomenon of negative skin friction and methods to predict the effects of negative skin friction. A shallow foundation under a deep, multiple level basement building structure may be deeper than a “deep” foundation below a structure without a basement. As in the case of shallow foundations, the design or static analysis of deep foundations consider the safety and performance of the foundation.
