  3. Abstract:
  4. In this article, behavior of cantilever retaining walls with various flexibilities, which retain saturated cohesive soil behind, is studied using numerical modeling. Generally, pattern of lateral earth pressure behind retaining walls is complex and this complexity becomes greater for clayey soils. In this investigation, effects of different wall bending stiffnesses, and backfill drainage conditions on the failure height and on the lateral earth pressure are investigated using finite elements. Comparison between the obtained results from numerical simulation and those based on empirical or conventional design methods indicate that soil-structure interaction and c drainage conditions play important roles in the analysis and design of flexible retaining walls which are not fully addressed in the classical methods of analysis. At the end of the paper advantages and limitations of the classical methods are discussed. © 2007 Taylor & Francis Group
