ABSTRACT
This chapter provides a general description to the construction of driven piles, the equipment used, and procedures applied. It describes the principles of dynamic formulas and wave equation analysis, and introduces their applications in preconstruction planning for driven pile installations. The chapter also introduces the techniques of pile driving analysis and their applications as a tool for quality assurance in pile driving. It explains the available methods and key issues related to the construction of bored piles. The chapter discusses the necessary quality assurance procedures involved during the construction of bored piles. It examines various types of axial and lateral pile load test methods, their principles, and interpretation of test results. One-dimensional wave equation that describes wave propagation through an elastic rod is more realistic in describing the dynamics of pile driving. The main purpose of the cushion between hammer and pile is to limit impact stresses in both the pile and the ram.
