Update the Pile Design by CPT Software to Incorporate Newly Developed Pile-CPT Methods and Other Design Features

The primary objectives of this research project are to collect all available pile load tests database from the Louisiana Department of Transportation and Development (LADOTD) and the corresponding Cone Penetration Test (CPT) soundings and soil borings close to test pile locations, and perform a screening based on soil condition and failure criteria during the load test, to compare between the measured and estimated pile resistance of the collected pile load tests database for all direct CPT methods, and perform statistical analyses to evaluate/rank the pile-CPT method(s) for use in Louisiana soil, to select, modify and/or develop a new pile-CPT method for use in the design of piles driven in Louisiana soils, re-calibration the resistance factor (ø) for all selected pile-CPT methods, to update the Louisiana Pile Design-Cone Penetration Test (LPD-CPT) software to incorporate the newly selected pile-CPT prediction methods, to update the “LPD-CPT” software to incorporate the effect of scour on soil properties and CPT data, and hence the long-term pile resistance and the pile set-u[ empirical equations into updated “LPD-CPT” software, incorporate the calibrated resistance factors (ø) for pile-CPT methods and pile set-up into the update “LPD-CPT” software in order to design the pile according to Load and Resistance Factor Design (LRFD) design methodology, and update the “LPD-CPT” software to be able to generate synthetic CPT profiles for all piles in the project.
