Comparison of measured pile capacity to pile capacity predictions made using electronic cone penetration data

This report contains comparisons of static pile load tests and pile capacity predictions generated from cone penetration test (CPT) data. Six CPT analytical methods were evaluated. They are referred to as: LPC Cone Method, Direct CPT Method, European Method, Schmertmann's Method, Cone-M Method and Bustamante's Method. Ultimate pile static capacity was defined using the Davisson criterion. Tested and predicted capacities for 19 bored and 13 driven piles are compared. Recommendations are made for the implementation of the more precise methods.
