Measured and Predicted Axial Response of 98 Piles
Additional Document Info
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 base was obtained from the Mississippi State Highway Department and was used to evaluate 13 methods designed to predict the ultimate load of a pile and five methods designed to predict the settlement of a pile. The methods include SPT/5., 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 that will minimize the cost of construction plus the cost of a potential failure. ASCE.
