Pile Design Based on Cone Penetration Test Results
The main objective of this research is to develop the methodology to determine pile load-carrying capacity based on the results of cone penetration test. The focus will be on the design of piles used to support typical transportation structures, with focus on the response of pile bearing on sandy soils to vertical loading. In order to develop the load-settlement curves for a variety of soil conditions, 3-D finite element modeling is used. In general, the pile response to an external load is strongly non-linear and may involve large irreversible deformations. For more realistic modeling of soil behavior around axially loaded piles, a non-linear elastic-plastic stress-strain relationship will be used in the finite element analyses. The calculated load-settlement curves are normalized with the cone resistance q(sub c) and the pile diameter B for the base resistance q(sub b) and the settlement s, respectively. The fully developed load-settlement curves in terms of q(sub b)/q(sub c) versus s/B can be used to determine the normalized pile base resistance q(sub b)/q(sub c) for any settlement-based design criterion. The results of the analyses are compared with results from calibration chamber plate load tests and free field pile load tests.
