A study was conducted to verify the design of a diaphragm wall with steel piles. The original design was based on analysis performed on a soil-structure interaction program using soil parameters calibrated in a previous study. Original and "as-built" design models were compared to measured results of the constructed structure. A second study was conducted to identify the sensitivity of moments and deflections to changes in wall stiffness and soil stiffness. A comparison of the effects of these changes was provided. / Master of Science
