Use 10 kN/m³ for the unit weight of water. Question 7 A site is underlain by a 6m thick saturated clay layer over rock. The unit weight of the clay is 22 kN/m³, the void ratio is 0.96, and and the consolidation parameters obtained from testing a sample obtained from a depth of 2m are: coefficient of consolidation = 0.015 m²/day, compression index = 0.3, recompression index = 0.02. A 2.5m thick sandy fill with unit weight = 20 kN/m³ will be placed on the site. Determine Zdr (express it in meters but write only the numeric answer in the text box).

**Use 10 kN/m³ for the unit weight of water.**
#### Question 7
A site is underlain by a 6m thick saturated clay layer over rock. The unit weight of the clay is 22 kN/m³, the void ratio is 0.96, and the consolidation parameters obtained from testing a sample obtained from a depth of 2m are: coefficient of consolidation \( C_v = 0.015 \, m²/day \), compression index \( C_c = 0.3 \), recompression index \( C_r = 0.02 \). A 2.5m thick sandy fill with unit weight \( \gamma_f = 20 \, kN/m³ \) will be placed on the site. Determine \( z_{dr} \) (express it in meters but write only the numeric answer in the text box).
\[ z_{dr} = \_ \]
Note to Students:
- Remember to use the provided unit weight of water when necessary.
- Ensure to review the concepts of consolidation and associated indices when solving for \( z_{dr} \).
This question is designed to test your understanding of soil mechanics, specifically the consolidation of clay under new loading conditions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7ef78748-0d90-4e21-b245-e231b14b3b61%2Fb471b890-a41c-4abb-950a-55ffb906eb95%2Fy1rvgxu_processed.png&w=3840&q=75)
