No settlement / improvement case yet

Add a settlement / improvement case to record its inputs, capacity and governing check.

Learning objectives

  • Compute consolidation settlement
  • Estimate time rate
  • Select ground improvement

Engineering judgment

  • Differential settlement damages structures, total settlement rarely does.
  • Check time rate against schedule.

Governing standards

  • NAVFAC DM-7

    Soil Mechanics and Foundations

    Bearing capacity, earth pressure, slope stability

    DM-7.01
