Application of Modified Terzaghi Theory in Deposited Sediment Consolidation
Deposited sediment shows significant large strain characteristics during weight consolidation with variable consolidation parameters. Non-neglected prediction errors will appear if applied classic Terzaghi theory in large strain consolidation calculation, especially as the settlement amount exceeds 50% which will lead to great coordinate errors and can't reflect the nonlinear features. In this paper, a new piece-consolidation model (based on modified Terzaghi theory) is proposed for deposited sediment consolidation prediction, of which large strain consolidation process is divided into a series of small strain consolidation, and each strain step consolidation is predicted by Terzaghi theory with necessary parameters modification. Power functional equation is applied for the constitutive relationship between permeability, compressibility and void ratio. With the assumption that each strain step consolidation coefficient is constant, large strain consolidation process can be determined by all the strain step settlement accumulation. Piece-consolidation model based on Terzaghi theory successfully meets the basic assumptions and reflects the nonlinear features. Moreover, model outputs also show a well agreement to the experimental measured.
