Most Upvoted Answer
Under a given load a clay layer attains 30% degree of consolidation in...
Explanation:
Solution:
- Definition: Degree of consolidation is a measure of the rate at which a soil layer consolidates under load.
- Formula: Degree of consolidation (U) = (eo - e)/(eo - er)
- eo: Initial void ratio
- e: Void ratio at any time t
- er: Void ratio of the soil particle
- Given: U30 = 0.3, t30 = 100 days
- To find: t60
Solution:
- Using the formula of degree of consolidation, we can write: U30 = (eo - e30)/(eo - er) = 0.3
- Similarly, at U60, we can write: U60 = (eo - e60)/(eo - er) = 0.6
- Dividing the above two equations, we get: (eo - e60)/(eo - er) / (eo - e30)/(eo - er) = 0.6/0.3
- Cancelling out er, we get: (eo - e60)/(eo - e30) = 2
- Further simplifying, we get: e60 = 2e30 - eo
- Now, we can use the time factor to determine the relation between eo, e30 and e60
- For a given soil, the time factor (Tv) can be defined as the time required for 50% consolidation to occur
- Using the formula for time factor, we get: Tv = (t30/t60)log[(1-U30)/(1-U60)] = 1
