Complementary Design Methodology for Driven Piles in Sand
Pile foundations have been distinguished as one of the favorable solutions for construction in difficult soil and structure conditions. The design of pile foundations primarily depends upon the function of pile whether to improve ground conditions, prevent slope movements, provide adequate bearing capacity, provide resistance to lateral loads, or resist uplift loads. The design of pile foundations should assure that the piles will effectively distribute or/and transfer the applied vertical load deep enough into to a higher effective stress level to provide the necessary resistance. The majority of current design formulas have been proposed for dynamic and pseudo-static loading conditions, and they suffer the absence of the physical soil-structure interaction. In this paper, a complementary design methodology is proposed for predicting the compressive load capacity of driven piles in sand. This method accounts for the post-driving residual stresses, level of effective stress, pile characteristics and incorporates the friction fatigue process as the pile penetrates into the soil. The method features statistical correlations that were formulated based on field testing data collected from previously published works. These correlations are verified using an independent database and by the use of other researchers. The proposed methodology was validated using the measured bearing capacities of 18 pile load tests, and was shown for the reasonable predictability and accuracy.
