Immediate and creep components of settlement  were determined and quantified during loading and consolidation stages respectively using  Field Deformation Analysis (FDA). Normalized equations were formulated from these  settlement components with special attention given to creep which is very important in  predicting long term settlement behaviors of embankments. Undrained shear strength,  coefficient of consolidation were back-calculated. Back-calculated undrained shear strength is  found to be more than two times of initial undrained shear strength at depth of 0 - 6m for all  embankments of NNH site by Feb. 1996 as all embankments reach a higher degree of  consolidation. Back-calculated Ch values decreases significantly with increasing effective  stress.  The embankment site were simulated by finite element method using CRISP to  compare the relative performance with respect to settlement, lateral deformation, and excess  pore pressure variation. The FEM analysis has many soil constitutive models, the Modified  Cam - Clay model inclusive. When creep settlement component is added to settlement  predicted by CRISP, this agreed almost with measured settlement. After correcting and adding  creep and immediate settlement components to settlement predicted by Terzaghi's theory of  consolidation, this also agreed with measured settlement. In February 1996, the observed  maximum surface settlement of TS3 was 7% and 14% higher than TS2 and TSl respectively.  Predicted pore pressuSchool of Civil Engineeringres appeared to have a similar trend to the measured values. A  normalized deformation behavior between lateral movements with depth and the settlements  with depth was established for all embankments of NNH site. 10aEmbankments1 aBalasubramaniam, A.S.,eChairperson1 aBergado, Dennes T.,eExamination Committee1 aKohgo, Y.,eExamination Committee  2 aThe Keidanren Foundation  (Federation of Japanese Business Organizations),eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
