DEVELOPMENT OF AN IMPROVED PILE DESIGN PROCEDURE FOR SINGLE PILES IN CLAYS AND SANDS. FINAL REPORT. APPENDIX P

This report deals with the prediction of the axial load carrying capacity of single piles in various soil conditions. The purpose is to evaluate thirteen selected prediction methods using a 100 pile data base which was obtained from the Mississippi Highway Department. The selected methods include SPT/Su methods, cone penetrometer methods, a pressuremeter method and a dynamic formula method. The data was organized on paper files and then on an IBM-PC diskette. Computer programs were then written to perform the selected methods. The methods were analyzed by comparing the predicted response to the measured response for each pile load test. A detailed analysis of each method was performed by analysing piles in different soil conditions separately and using limiting values for the point resistance. Five methods which predict the entire load-settlement behavior were analyzed for predicted settlement at working loads. A risk analysis method is presented to show the importance of properly selecting safety factors. Appendix P is the user's manual for COYLE; a computer program that computes ultimate capacity versus depth and load versus settlement for axially loaded piles using H.M. Coyle's method.
