Settlement due to Consolidation

Abstract

Settlement of the trial embankments placed on the campus of Asian Institute of Technology by (a) Akagi and (b) Ohta is discussed based on the performance of various settlement estimate techniques. Since these embankments were placed close to each other, mechanical parameters of the subsoil should be identical in both cases and therefore gives good chance to check the appropriateness and reliability of parameter estimation procedure. In addition to comparing the settlement estimate methods, proposed is a laboratory technique to estimate the in-situ effective stress state. This technique gives information on the change in effective stress state due to the progress of consolidation settlement.
