Variables Used

Allowable Design Load on Rock Socket - (Measured in Pascal) - Allowable Design Load on Rock Socket is the max load that a rock socketed foundation element, can safely support without exceeding the rock’s bearing capacity or causing unacceptable settlement.
Socket Diameter - (Measured in Meter) - Socket Diameter is the diameter of the cavity or hole created in the ground or rock into which a pile or foundation element is inserted or placed.
Socket Length - (Measured in Meter) - Socket Length is the depth or length of a borehole or excavation in which a foundation element, such as a pile or a drilled shaft, is embedded or seated.
Allowable Concrete-Rock Bond Stress - (Measured in Pascal) - Allowable Concrete-Rock Bond Stress is the maximum shear stress that can be safely transferred from concrete to rock at their interface without causing a failure.
Allowable Bearing Pressure on Rock - (Measured in Pascal) - Allowable Bearing Pressure on Rock is the maximum pressure that can be applied to the surface of a rock mass without causing unacceptable settlement or failure of the rock.

STEP 1: Convert Input(s) to Base Unit

Socket Diameter: 0.5 Meter --> 0.5 Meter No Conversion Required
Socket Length: 2 Meter --> 2 Meter No Conversion Required
Allowable Concrete-Rock Bond Stress: 2 Megapascal --> 2000000 Pascal (Check conversion here)
Allowable Bearing Pressure on Rock: 18.92 Megapascal --> 18920000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_d = (pi*d_s*L_s*f_g)+((pi*(d_s^2)*q_a)/4) --> (pi*0.5*2*2000000)+((pi*(0.5^2)*18920000)/4)

Evaluating ... ...

Q_d = 9998118.62004952

STEP 3: Convert Result to Output's Unit

9998118.62004952 Pascal -->9.99811862004952 Megapascal (Check conversion here)

FINAL ANSWER

9.99811862004952 ≈ 9.998119 Megapascal <-- Allowable Design Load on Rock Socket

What is Deign Load?

the design load is the maximum amount of something a system is designed to handle or the maximum amount of something that the system can produce, which are very different meanings. For example, a crane with a design load of 20 tons is designed to be able to lift loads that weigh 20 tons or less.
