Numerical analysis of liquefaction affected shallow foundations performance on improved ground.
  A novel numerical methodology is presented and used to simulate the seismic response of footings on liquefiable ground, locally improved in order to reduce settlements and increase the bearing capacity of the foundation. The numerical simulation adopts the non-linear Finite Difference code FLAC-3D (v.4.0), combined with the NTUA Sand constitutive model, which has been developed at the Foundation Engineering Laboratory of NTUA in order to predict the cyclic response and liquefaction resistance of sands, on the basis of Critical State soil plasticity. The proposed methodology is evaluated through comparative application to the well documented centrifuge experiments of Liu & Dobry (1997).
