This theses will evaluate the accuracy of the electrical and mechanical cone penetration test for predicting pile capacity when compared to observed pile capacity results from nearby pile load tests. The research was accomplished by finding former construction sites which had pile load test, electrical cone penetration test, mechanical cone penetration test, and boring log data all located within a close proximity of one another. Pile capacities were predicted using the electrical and mechanical cone penetration test sounding data. Then the predicted pile capacities were compared to the observed pile capacity determined by nearby pile load tests. As a natural consequence of performing the latter analysis, comparisons could also be made between the results of electrical and mechanical cone penetration tests at a given site. Soil layer divisions along with the average friction ratio and end bearing resistance measurements in each layer were identified and compared from electrical and mechanical cone penetration test sounding data. Computer programs, designated MCPTUFR and PLAID, were developed to predict pile capacity using conventional methods from mechanical and electrical cone penetration tests respectively. Theses.
