Question

The vulnerability of soil types to a mechanical stress process (same intensity and magnitude) is different. Explain why.

Answer 1

As per understandung of mine. In question you are asking about why different types of soil act in different way on application of mechanical stress. Why this happen?? It is explained as below.

There exist different type of structure of soil explained as below:-

Coarse grained structure:- The structure is found for soils havubh particles size greater than 0.02 mm i.e. for coarse grained soil. Example sand and gravel. In this type of formation gravotational forces play predominant role and electrical forces are insignificant.

Honey combed structure:- structure is found for soil having particle size of range of 0.0002 mm to 0.02 mm for example silt and clay. In this type of formation both gravitational and electircal forces are significant.

Disperesed and floculant structure:- This structure is found for soil having particles size less than 0.0002 mm i.e. fine clay and colloids. In this type structure electrical forces are predominant.

Therefore as explained above there are different type of soil structures in different types of soils therefore they will act different under mechanical stress of same intensity and magnitude.
