q _m = (2*P)/(3*L*((B/2)-e_load))
This formula uses 5 Variables

Variables Used

Maximum Soil Pressure - (Measured in Pascal) - Maximum Soil Pressure is the net intensity which is considered the ultimate bearing-capacity based on the quantity, settlement expected and the capability of a structure to bear this settlement.
Axial Load on Soil - (Measured in Newton) - Axial Load on Soil is defined as applying a force on a foundation directly along an axis of the foundation.
Length of Footing - (Measured in Meter) - Length of Footing is the length of the larger dimension of the footing.
Width of Footing - (Measured in Meter) - Width of Footing is the shorter dimension of the footing.
Eccentricity of the Load on Soil - (Measured in Meter) - Eccentricity of the Load on Soil is the distance from the center of gravity of the column section to the center of gravity of the applied load.

STEP 1: Convert Input(s) to Base Unit

Axial Load on Soil: 631.99 Kilonewton --> 631990 Newton (Check conversion here)
Length of Footing: 4 Meter --> 4 Meter No Conversion Required
Width of Footing: 2 Meter --> 2 Meter No Conversion Required

What is Soil Pressure?

Soil pressure is also known as the earth pressure. Pressure is defined as external load applied on the body causing a stress, which is measured in terms of force per unit area. Similarly, the soil pressure is expressed as the forced applied by a soil mass (backfill) over the retaining wall, in the lateral direction throughout its depth.
