DEVELOPMENT OF AN IMPROVED PILE DESIGN PROCEDURE FOR SINGLE PILES IN CLAYS AND SANDS. EXECUTIVE SUMMARY
This article deals with the prediction of the response to monotonic axial loading of single piles in various soil conditions. A 98 pile load test data was obtained from the Mississippi State Highway Department and was used to evaluate 13 methods to predict the ultimate load of a pile and 5 methods to predict the settlement of a pile. The selected methods include SPT/S sub u methods, cone penetrometer methods, a pressuremeter method, and a dynamic formula method. The accuracy and precision of each method is quantified statistically and a risk analysis is performed in order to properly assess the factor of safety. A cost analysis is also performed in order to find the factor of safety which will minimize the cost of construction plus the cost of a potential failure.
