Key words: Pliocene clays, liquidity index, effects of secondary consolidation and overconsolidation with a liquidity index close to unity. plasticity index observed in normally consolidated "aged". The values of bulk unit weights and Atterberg Limits of Klang Clay are shown of Klang Clay increases almost linearly with depth after the overconsolidated top.

The Liquidity Index (LI) and Consistency Index (CI) • The relative consistency of a cohesive soil in the natural state can be defined by a ratio called the liquidity index (LI), which is given by: • The in situ moisture content for a sensitive clay may be greater than the liquid limit. Ruwan Rajapakse PE, CCM, CCE, AVS, in Geotechnical Engineering Calculations and Rules of Thumb (Second Edition), 2016. 5.4 Overconsolidation ratio. Overconsolidation ratio is defined as the ratio of past maximum stress and present existing stress. The existing stress in a soil can be computed based on the effective stress method. The overconsolidation ratio of eemian gyttja determination. The overconsolidation ratio is an important parameter that determines the value of stress history exerted in the past on the subsoil in 0 0 v OCR k qt v σ σ ′ − =⋅ (2) where k is the overconsolidation factor with a range of 0.3 to 0.5 and σv0 is the vertical geostatic stress. For intact clays, a first-order estimate of the preconsolidation stress can be obtained from net cone tip resistance used k = 0.33 (see [2]).
