Table 25.16. Modified secondary compression index of peat, organic soil, and clay from oedometer tests
Webconsolidation is referred to as secondary compression — a process where deformation continues within a soil mass under a constant applied stress (which is also the effective … WebConsolidation of soil (normally consolidated) can be evaluated from the following equation as discussed in this article. S c = C c H c /(1+e 0) log[(σ’ 0 +Δσ’ av)/σ’ 0]. Where. S c – consolidation settlement in the normally consolidated clay. C c – Compression index – to be evaluated from the laboratory testing. H c – Height of the clay layer. e 0 – Initial void ratio …
WebSoil consolidation refers to the mechanical process by which soil changes volume gradually in response to a change in pressure. This happens because soil is a two-phase material, …
