Given Information:
- Thickness of clay layer = 20m
- Settlement in 2 years = 10mm
- Coefficient of consolidation = 0.004 cm2/s
Calculating Time Factor:
The time factor (T) is given by the equation:
T = (t⋅Cv) / (H^2)
where:
- t = time in seconds
- Cv = coefficient of consolidation in cm2/s
- H = thickness of clay layer in cm
Converting the given values:
- t = 2 years = 2⋅365⋅24⋅60⋅60 seconds
- Cv = 0.004 cm2/s
- H = 20m = 20⋅100 cm
Substituting the values:
T = (2⋅365⋅24⋅60⋅60⋅0.004) / (20⋅100⋅20⋅100)
T = 0.00047304
Calculating Time Factor for Desired Settlement:
The desired settlement is 15mm. Let's assume it will occur in t1 years.
Using the equation:
T1 = (t1⋅Cv) / (H^2)
Rearranging the equation:
t1 = (T1⋅H^2) / Cv
Substituting the values:
t1 = (0.00047304⋅(20⋅100)⋅(20⋅100)) / 0.004
t1 = 2.3652 years
Therefore, the deposit will experience a total settlement of 15mm in the next 2.3652 years. Rounding off to the nearest year, the answer is 2.5 years.
- Thickness of clay layer = 20m
- Settlement in 2 years = 10mm
- Coefficient of consolidation = 0.004 cm2/s

Substituting the values:

T = 0.00047304
Calculating Time Factor for Desired Settlement:
The desired settlement is 15mm. Let's assume it will occur in t1 years.
Using the equation:
T1 = (t1⋅Cv) / (H^2)

t1 = 2.3652 years
Therefore, the deposit will experience a total settlement of 15mm in the next 2.3652 years. Rounding off to the nearest year, the answer is 2.5 years.
