C. W. Hall, pp 444. 2000.〕 More specifically, Karl von Terzaghi's Principle, also known as Terzaghi's theory of one-dimensional consolidation, states that all quantifiable changes in stress to a soil (deformation, shear resistance ) are a direct result of a change in effective stress. The effective stress $\backslash sigma\text{'}$ is related to total stress $\backslash sigma$ and the pore pressure $u$ by the relationship; :$\backslash sigma\; =\; \backslash sigma\text{'}\; +\; u$ reading that total stress is equal to the sum of effective stress and pore water pressure. == Assumptions of Terzaghi's Principle == # The soil is homogenous (uniform in composition throughout). # The soil is fully saturated (zero air voids due to water content being so high). # The solid particles and water are incompressible. # Compression and flow are one-dimensional (vertical axis being the one of interest). # Strains in the soil are relatively small. # Darcy's Law is valid for all hydraulic gradients. # The coefficient of permeability and the coefficient of volume compressibility remain constant throughout the process. # There is a unique relationship, independent of time, between the void ratio and effective stress 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Terzaghi's principle」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
