Abstract: Results from the computational driving of a concrete pile below a prebored hole (referred to as a “prebored” pile for convenience) in an undrained, normally consolidated clayey soil are presented. The analysis uses a nonlinear, finite-element model that simulates the penetration of the pile into the soil. The response of the pile-soil system is examined at various preboring levels. A comparison between the responses of normally consolidated clays with various strengths is discussed. The influence of pile-soil friction and tip bearing on the response is also investigated. Emphasis is placed on the evolution of the state of stress in the soil and the development of pore-water pressure in the course of driving. Other computations are made for the case where the pile is driven some distance into undisturbed soil, referred to as a “driven” pile case for convenience. Finally, insight is gained into the difference in response between prebored and driven piles.
