Webgreater degree of compressibility. Values of compression index C c vary for different type of soils. Table 1 below indicates compression index C c valves of several kind of soils: Kind of soil compression index C c Dense sand 0.0005- 0.01 Loose sand 0.025- 0.05 Firm clay 0.03- 0.06 Stiff clay 0.06- 0.15 Medium soft clay 0.15- 1.0 WebFor normally consolidated clay layer in the field, the ff. values are given: Thickness of clay layer = 8.5ft, Void Ratio = 0.8; Compression Index = 0.28; Average effective pressure on the clay layer is 2650 lb/ft2; ∆σ = 970 lb/ft2; Secondary Compression index = 0.02.
An energy-based isotropic compression relation for cement-admixed soft clay
WebOct 15, 2014 · The results obtained from consolidation tests demonstrate linear e−logσ v relationships for Shanghai clay at normally consolidated state, while partly or even global non-linear relationships for Dalian clay. The compression index C c for both clays follows the correlation of C c = 0.009(w L −10) where w L is the liquid limit of soil. WebMar 20, 2024 · The compression index (Cc) is the slope of the linear portion of the pressure–void ratio curve on a semi-log plot, with pressure on the log scale (IS: 8009 – Part 1, 1976). This is a dimensionless parameter. For any two points on the linear portion of the plot-. C c = e o − e 1 log ( p 1 p o) Where. p o and p 1 are pressures corresponding ... haflinger at classic slippers womens
