Abstract

In one-dimensional consolidation of fibrous peat, it is known that the behavior can not be sufficiently explained by Terzaghi theory. In this study, based on the fact that the pore of fibrous peat consists of macro (outer) pore between organic bodies and micro (inner) pore inside organic bodies, an approximate analytical method for one-dimensional consolidation of fibrous 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 data.

An Analytical Prediction of Consolidation Settlement of Fibrous Peat Deposit Under Loading

St. Louis, Missouri

In one-dimensional consolidation of fibrous peat, it is known that the behavior can not be sufficiently explained by Terzaghi theory. In this study, based on the fact that the pore of fibrous peat consists of macro (outer) pore between organic bodies and micro (inner) pore inside organic bodies, an approximate analytical method for one-dimensional consolidation of fibrous 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 data.
