How to Measure the Compressibility of Soils? | Soil ...

Hence, the compressibility of soils is expressed in the terms of a plot between void ratio on the y-axis and effective stress on the x-axis. Void ratio is used to represent compression because it is a ratio of the volume of voids to the volume of solids, the former being reflective of compression and the latter being constant in soil compression.

Undrained compressibility characteristics and pore ...

Soil conditioning with foam is widely used to transform natural soil into the desired state suitable for mechanised tunnelling. Since the excavated soil is rapidly discharged out with little water drained during earth pressure balance (EPB) shield tunnelling, it is necessary to investigate the undrained compressibility characteristics of foam-conditioned soil under chamber pressure.

Compression and Consolidation of soils

Compressibility Characteristics Soils are often subjected to uniform loading over large areas, such as from wide foundations, fills or embankments. Under such conditions, the soil which is remote from the edges of the loaded area undergoes vertical strain, but no horizontal strain. Thus, the settlement occurs only in one-dimension.
