• Abstract:
  The Wisconsin Department of Transportation (WisDOT) occasionally constructs
  
  embankments and retaining walls over compressible materials using staged construction.
  
  Staged construction is a technique used to build an embankment or retaining wall in stages,
  
  allowing the compressible and weak soil to consolidate and gain strength over time. As part of
  
  the staged construction, the fill placement is instrumented and monitored for pore water pressure,
  
  settlement and lateral deflection. The construction of tall embankments or retaining walls on soft
  
  soils typically requires staged construction, which leads to an increase in effective stress, reduction
  
  in void ratio and settlement and gain in shear strength. However, tall embankments are not fully
  
  constrained, contributing to the potential of global failure of the foundation soil and generation of
  
  lateral movements that magnify vertical settlements of the embankments.
