Ultimate Bearing Capacity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Ultimate Bearing Capacity = Net Ultimate Bearing Capacity of Soil+Effective Surcharge in Kilo Pascal
q_f = q_net+σ_s
This formula uses 3 Variables

Variables Used

Ultimate Bearing Capacity - (Measured in Pascal) - Ultimate Bearing Capacity is defined as the minimum gross pressure intensity at the base of the foundation at which the soil fails in shear.
Net Ultimate Bearing Capacity of Soil - (Measured in Pascal) - Net Ultimate Bearing Capacity of Soil is the minimum net pressure intensity causing shear failure.
Effective Surcharge in Kilo Pascal - (Measured in Pascal) - Effective Surcharge in Kilo Pascal also called as surcharge load refers to the vertical pressure or any load that acts over the ground surface additional to basic earth pressure.

STEP 1: Convert Input(s) to Base Unit

Net Ultimate Bearing Capacity of Soil: 38.3 Kilonewton per Square Meter --> 38300 Pascal (Check conversion here)
Effective Surcharge in Kilo Pascal: 0.45 Kilonewton per Square Meter --> 450 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

q_f = q_net+σ_s --> 38300+450

Evaluating ... ...

q_f = 38750

STEP 3: Convert Result to Output's Unit

38750 Pascal -->38.75 Kilopascal (Check conversion here)

FINAL ANSWER

38.75 Kilopascal <-- Ultimate Bearing Capacity
