• 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.
