Application of the Phase Change Process to One-Dimensinal Consolidation Behavior of Peat

by Keiji Kogure, Natl Defense Acad, Yokosuka, Japan,



Document Type: Proceeding Paper

Part of: Vertical and Horizontal Deformations of Foundations and Embankments

Abstract:

In this study, based on the fact that the pore of fibrous peat consists of the macro (outer) pore between organic matters and the micro (inner) pore inside organic matter, an approximate analytical method for the prediction of the one-dimensional consolidation settlement of peat is presented. The macro pore consolidation (MAC) resulting from dewatering from the macro pore begins in the first place and the peat collapses to a new void ratio. At the same time, the micro pore consolidation (MIC) resulting from dewatering from the micro pore continuously starts to a final void ratio. The total settlement is given from the summing those by MAC and MIC. The proposed method is compared with field observational data and it is seen that the proposed model gives settlement result that follow quite closely the field data.
