Analysis of a River Bank, Levee, or Floodplain I-Wall Embedded in Stratified Soil Layers During Flood Events Using Corps_I-Wall (CI-Wall) Version 2.0
Abstract
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 Corps_I-Wall Version 2.0. The executable program is referred to as CI-Wall. This version of Corps_I-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 Corps_I-Wall software capabilities for engineering analysis include total stress and/or 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 Corps_I-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.
