Abstract

Results from nineteen full-scale axial load tests are reviewed to compare methods for predicting axial capacities of drilled shafts using results of Cone Penetration Tests (CPT). The three methods to estimate failure loads are: (1) Nottingham method, (2) Laboratoire des Ponts et Chaussees method (LPC), and (3) the Poulos and Davis method. Comparisons are made to assess the accuracy and dependability of each predictive method. Analyses of results indicate that the LPC method provides the most reliable predictions for axial capacities of drilled shafts in clay.

Prediction of Drilled Shafts Axial Capacities Using CPT Results

St. Louis, Missouri
