Explain Limitation of Consolidation Theory.

The value of the coefficient of consolidation has been assumed to be constant. However, in reality, it changes with change in the consideration pressur.

 The distance `d` of the drainage path cannot be measured accurately in the field.

 There is sometimes difficulty in locating the drainage face. 

The equation is based on the assumption that the consolidation is one dimensional. In field, the consolidation is generally three-dimensional.

 The initial consolidation in the secondary consolidation have been neglected. Sometimes, these form an important part of the total consideration.

 In the field, the load is seldom applied instantaneously. The effect of the loading period has to be considered.

 In actual practice, the pressure distribution may be far from linear or uniform. The theory become complicated when correct distr....
