Normally consolidated line
Web8 de jan. de 2024 · Since the specimen has no volume change, the void ratio is constant during undrained shearing. The solid lines denote the normally consolidated line (NCL) and the critical state line (CSL). NCL is related to the volumetric response under isotropic compression loading, whereas CSL is corresponding to the volume of specimens at a … WebFor a normally consolidated clay, there is a unique relationship between the specific volume and the effective stress, defined by the normal consolidation line in the (p ′, υ)-plane. For an overconsolidated clay, there may be a range of voids ratios for a given effective stress, depending on the preconsolidation stress from which the material was unloaded.
