Behavior of floodwall systems is studied by a comprehensive analysis procedure to understand the soil-structure interaction mechanisms involved in these systems. The procedure uses the finite element method equipped with suitable models of the soil-structure interface, nonlinear soil behavior, and loading sequence. A full scale test, performed by the New Orleans District, U.S. Corps of Engineers, on a test section near an existing levee was used for verification of the analytical model. The analytical tool permitted the study of a variety of floodwall/levee configurations to obtain information on the behavior of floodwalls leading to the development of improved design-oriented analysis procedures.
