Session 01: Case Histories of Unexpected Behavior and Failure of Shallow, Deep and Other Foundations

Abstract
The analysis of ogee shaped barrage raft floor is a challenging task for the designers because of varying heterogeneous strata disposition, worst combination of loading conditions and functional requirements. A typical Indian barrage bay 3 and 4 has been chosen for analytical comparison between conventional and numerical approach. The behavior of ogee shaped barrage raft floor under representative load cases highlighted that conventional analytical approach i.e. Hetenyi’s method may prove to be inadequate for varying foundation media, which has been recommended by Indian standard code. Unlike the analytical approach, the numerical approach of analysis especially the finite element method with the help of digital computers is capable of accounting for the variation in foundation media, which is a pointer to the advantage of numerical modeling approach of analysis of a typical barrage structure especially the ogee shaped barrage raft floor. The conventional and numerical approaches have been compared to show the limitations of conventional approach and their implication on design estimates.
