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 Web9-4 σv = σ1, σ2 ≠ 0, σ3 = 0 and ε2 = 0 , ε3 ≠ 0 For this case it may be shown that σ1 ε1 E (1-υ2) (9.5) and the settlement ρ becomes ρ = ε1 L = σ1 L E (1 −υ2) (9.6) The settlements calculated from equations (9.4), (9.6) and (9.1) for the laterally confined, partly
