Is given as 0.8.
To calculate the bearing capacity of the clay deposit, we can use the following formula:
Q = c * A * Nc * Nq * Nγ
Where:
Q = Ultimate bearing capacity
c = Cohesion of the clay deposit (5 kN/m2)
A = Area of the square pile (30 cm x 30 cm = 900 cm2 = 0.09 m2)
Nc = Bearing capacity factor based on cohesion (provided value is missing)
Nq = Bearing capacity factor based on surcharge (provided value is missing)
Nγ = Bearing capacity factor based on unit weight (provided value is missing)
Since the values for Nc, Nq, and Nγ are not provided, we cannot calculate the ultimate bearing capacity.
The mobilizing factor of 0.8 is typically used to calculate the allowable bearing capacity, which is the safe load that can be applied to the pile without causing failure. The allowable bearing capacity is usually a fraction of the ultimate bearing capacity, determined by factors such as safety factors and the expected settlement criteria.
To calculate the allowable bearing capacity, we can use the following formula:
Qallowable = Qultimate / Factor of Safety
Since the ultimate bearing capacity is unknown, we cannot calculate the allowable bearing capacity without the missing values for Nc, Nq, and Nγ.
