The purpose of the I-Wall Analysis Research and Development R and D effort is to provide the U.S. Army Corps of Engineers USACE districts with essential tools in analyzing and evaluating I-Wall performance in riverine, fluvial, and coastal environments. This report summarizes an engineering method and its implementation in the software CorpsI-Wall Version 2.0. The executable program is referred to as CI-Wall. This version of CorpsI-Wall is used for the design of new I-Walls or the analysis of existing I-Walls in floodplains i.e., level ground or in riverbanks and levees i.e., in non-level ground, with non-level soil layers and non-level piezometric surfaces during flood loading. Other CorpsI-Wall software capabilities for engineering analysis include total stress andor effective stress earth pressure calculations by either 1 the Coefficient Method of analysis, or by 2 the Wedge Solution Method of analysis. The program accounts for gap initiation and propagation by invoking a hydraulic fracturing criteria. It also allows for pseudo-static modeling of wave loading of coastal structures. Probabilistic analysis is a primary component of CorpsI-Wall for new and existing I-Wall analysis. Examples are provided to highlight each of these capabilities and a users manual for using the Graphical User Interface GUI for CI-Wall is included.
