“…For saturated soils, the parameters required to define the model are k, K and M and they are related to the usual soil parameters as shown in Table 3. The computed average values of k and K for this sandy clayey silt (Table 3) are within the range for soils with similar Atterberg limits (Nakase et al, 1988;Sivakugan, 1990;Toll and Ong, 2003). The values of M c and M e are generally higher than those for clays but within the limits for plastic silts (Nakase et al, 1988).…”

A detailed study was performed to investigate the compressibility and the shear strength of a residual soil in Omdurman, Sudan. The soil resulted from weathering of sandstone and mudstone. The soil is classified as sandy clayey silt (MH-CH) and is generally partially saturated. Consolidation tests were performed to study the compressibility of the soil and UU, CIU and insitu tests (CPT and SPT) were performed to study the shear strength characteristics of the soil. The characteristics of this residual soil can generally be predicted using correlations proposed in the literature for transported soils. The soil is of low to medium compressibility and exhibits slight apparent overconsolidation behavior. The soil dilates during shear and shows no long term effective cohesion. Problems associated with open cuts in this soil are attributed to loss of strength upon saturation.

“…For instance, Casagrande's A-Line classifies soils into clays and silts based on a correlation between soil type and a combination of liquid limit and plasticity index (Casagrande, 1947). The plasticity index has been used to predict undrained strength ratios (Skempton, 1954(Skempton, & 1957; the ratio of strength to Standard Penetration Test (SPT) blowcount (Stroud, 1974) and critical state soil parameters (Schofield & Wroth, 1968& Nakase et al 1988. Black (1962) used the plasticity characteristics of clays to develop predictions for the California Bearing Ratio (CBR) -another famous soil index parameter to describe road subgrade quality which has been traditionally related to soil modulus for use in road pavement design (e.g.…”

“…These Atterberg limits have been used for numerous purposes, including the estimation of shear strength, deformation and critical-state soil mechanics parameter values (e.g. Skempton, 1944Skempton, , 1954Skempton, , 1957Karlsson & Viberg, 1967;Stroud, 1974;Wroth, 1979;Carrier & Beckman, 1984;Larsson et al, 1987;Nakase et al, 1988;Wood, 1990;Tripathy & Mishra, 2011;Sørensen & Okkels, 2013;Farias & Llano-Serna, 2016). The liquidity index (I L ) parameter is used in codified design approaches for deep foundations in Russia (see Vardanega et al, 2012;Vardanega & Haigh, 2014a;Kolodiy et al, 2015) and in geomorphological research to characterise soils at a more regional level (e.g.…”

Use of fall cones to determine Atterberg limits: a review

2018

View full text Add to dashboard Cite

This paper reviews the percussion-cup liquid limit, thread-rolling plastic limit (PL) and various fall-cone and other approaches employed for consistency limit determinations on fine-grained soil, highlighting their use and misuse for soil classification purposes and in existing correlations. As the PL does not correspond to a unique value of remoulded undrained shear strength, there is no scientific reason why PL measurements obtained using the thread-rolling and shear-strength-based fall-cone or extrusion methods should coincide. Various correlations are established relating liquid limit values deduced using the percussion-cup and fall-cone approaches. The significance of differences in the strain-rate dependency on the mobilised fall-cone shear strength is reviewed. The paper concludes with recommendations on the standardisation of international codes and the wider use of the fall-cone approach for soft to medium-stiff clays in establishing the strength variability with changing water content and further index parameters.
