Electronic Theses and Dissertations
The objective of this study was to re-examine some but the crucial established failure mechanism, and also to establish other failure mechanisms of the floodwalls due to hurricanes in New Orleans so that the necessary retrofitting techniques could be sought out. Depending on the failure mechanisms, two of the proposed retrofitting techniques such as "structural cap" to maintain integrity by tying adjacent panels of I-type floodwalls, and "bentonite apron" to self seal gaps that occur between the floodwall and foundation soil were chosen, for which their performances had to be evaluated. This dissertation documents all the numerical analysis conducted to …
