Normally consolidated line
WebThe distance from the normal consolidation line has an important influence on soil behaviour. This is described numerically by the overconsolidation ratio (OCR), which is defined as the ratio of the preconsolidation stress to the current effective stress. Note that when the soil is normally consolidated, OCR = 1 WebExperimental results are presented in this note to study the coefficient of lateral earth pressure at rest, K0, of sand measured using a plane-strain apparatus. The data are …

WebThis paper first presents a unique relationship between permeability and void ratio. This relationship is then used for deriving the governing differential equation of consolidation for normally consolidated soils where void ratio vs. logarithm of effective stress can be approximated by a straight line. WebIn this lecture, I discuss how to compute stress paths for drained and undrained loading in p' and q space, as well as void ratio and p' space. I discuss the...

Web29 de ago. de 2024 · August 29, 2024. During the shear strength test of soils using a triaxial machine, one of the major ways of monitoring stress changes is by showing the Mohr’s stress circles at different stages of loading/unloading. However, this may be difficult to plot as well as confusing when a number of circles are to be shown in the same diagram.
