Plate bearing test with 20 cm diameter plate on soil subgrade yielded ...
Given Data:
Diameter of plate = 20 cm
Pressure at 0.5 cm deflection = 1.25 x 105 N/m2
Concept:
The elastic modulus of subgrade can be calculated by the following formula:
Es = (4Q/πD2) / δ
Where,
Es = Elastic Modulus of subgrade
Q = Load applied on the plate (N)
D = Diameter of the plate (m)
δ = Deflection of the plate (m)
Calculation:
As per the given data, the load applied on the plate is not given. Therefore, we cannot calculate the elastic modulus of the subgrade.
Hence, the correct answer is option 'D' (None).
