Behavior of Overconsolidated Clay


Normal versus overconsolidated clay behavior
Normal versus Overconsolidated clay behavior

  • Clay retains a “memory” of its load history

  • The effective cohesion of overconsolidated clay can be significant

  • The effective cohesion can be lost through subsequent wetting, especially, load cycling with moisture


  • Mohr Circle plot of a typical overconsolidated clay soil, illustrating the artificially high cohesion engendered by tortuous desiccation. Note the apparent preconsolidation pressure caused by the severe shrinkage.
