Civil Engineering ⇒ Topic : Terzaghis one dimensional consolidation theory
|The one dimensional consolidation theory
proposed by Karl Terzaghi in 1923, is based on
the following assumptions|
1. The soil is homogeneous.
2. The soil is 100% saturated.
3. The drainage and consolidation both are one dimensional.
4. The compressibility of soil grains and water is practically nil.
5. The soil is laterally confined.
6. The Darcy's law is void.
7. The coefficient of permeability is constant during the process of consolidation.
8. The time lag of consolidation is entirely due to low permeability of the soil.
9. The change in the effective pressure in the soil causes corresponding change in void ratio.
10. The change in thickness of the layer during consolidation in insignificant.
11. Constant values for certain soil properties remains constant.
