Furthermore, the derived strength and compressibility parameters were used in  the prediction of the stability and settlement of full scale test embankments.  Samples from both split-spoon and Shelby tube samplers were tested in  unconfined compression and unconsolidated undrained triaxial tests. Three  oedometer and three Rowe cell consolidation tests were also performed to  determine the compressibility of soil. In the field, four field vane shear tests  and two screw plate load tests were conducted.  The undrained strength from split-spoon samples are slightly higher than  the samples from shelby tube. The ratio between Cv(field} to Cv(lab) ranges from  1. 7 to 11. The Cv values derived from Rowe cell consolidometer are in better  agreement to the field values than those derived from the conventional oedometer  tests. Moreover, the embankment settlement prediction was performed using the  parameters derived from oedometer, Rowe cell, screw plate load tests as well as  the Asaoka's graphical method. The Asaoka's graphical method fits best with the  actual settlement. The settlement prediction using the derived compressibility  parameters from Rowe cell agrees very well with the observed data. Oedometer  yielded the most conservative prediction. Furthermore, the UU and corrected  field vane undrained strengths are in good agreement with the actual strengths  mobilized in the field. The corrected strengths obtained from UC tests gave a  reasonable prediction of the factor of safety. Moreover, the corrected UU  strengths from split-spoon gave a slightly higher prediction. Other methods from  MESRI (1975) and SHANSEP (LADD & FOOT, 1974) were also considered in which  both predicted the embankment stability very well. 0aSoilsxTesting1 aBergado, Dennes T.,eChairperson1 aBalasubramaniam, A.S.,eExamination Committee1 aSugimoto, M., eExamination Committee2 aGovernment of New Zealand, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
