Critical State Soil Mechanics (Geotechnical Design) - Assignment Example

esting, one study established the shear apparatus that the successive students used in studying the conditional changes in the shear zone both in clay and sand soils. Another study that obtained the soil ob the Cambridge data of a simple apparatus of shear test and on triaxial tests resulted into the publication of a critical state concept.
The critical state theory was developed from the understanding of the soils that go through shearing. In the mechanics of the critical soil, clear shear strength would be showed when the soil experiences the shear at a constant volume, which is referred to as the critical state (Figure 1) (Heyman, 2008).
In this case, there are three identified shear strengths for a soil that goes through shear. These are the peak strength, constant volume strength or the critical state, and the residual strength. Peak strength happens at a critical state depending on some initial state of the particles of soil that are sheared.
