Abstract : Prior to performing twenty-eight axial and two lateral load tests on piles at Mississippi the Lock and Dam 26 project, an in situ test program was conducted. The program consisted of four cone penetration tests, twelve pressuremeter test borings, and four standard penetration test borings. Comparisons of pile capacity predictions were made for each of the in situ test methods. The initial study generated four reports and voluminous test data. This is a summary of those reports.
