Total Downward Force on Soil when Resultant is Outside Middle Third Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Downward Force on Soil = (Earth Pressure*3*Middle Third Distance)/2
R_v = (p*3*a)/2
This formula uses 3 Variables

Variables Used

Total Downward Force on Soil - (Measured in Newton) - Total Downward Force on Soil is the net force on soil in the vertical direction.
Earth Pressure - (Measured in Pascal) - Earth Pressure is the lateral pressure exerted by the soil on a shoring system. It is dependent on the soil structure and the interaction or movement with the retaining system.
Middle Third Distance - (Measured in Meter) - Middle Third Distance is the one-third of the total length or a=L/3.

STEP 1: Convert Input(s) to Base Unit

Earth Pressure: 83.3 Pascal --> 83.3 Pascal No Conversion Required
Middle Third Distance: 4 Meter --> 4 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_v = (p*3*a)/2 --> (83.3*3*4)/2

Evaluating ... ...

R_v = 499.8

Earth Thrust Horizontal Component given Sum of Righting Moments

Go Horizontal Component of Earth Thrust = ((Coefficient of Sliding Friction*Total Downward Force on Soil)/1.5)

Total Downward Force on Soil for Horizontal Component

Go Total Downward Force on Soil = (Horizontal Component of Earth Thrust*1.5)/Coefficient of Sliding Friction

Total Downward Force on Soil when Resultant is Outside Middle Third

Go Total Downward Force on Soil = (Earth Pressure*3*Middle Third Distance)/2

Pressure when Resultant is Outside Middle Third

Go Earth Pressure = 2*Total Downward Force on Soil/(3*Middle Third Distance)

Resultant Outside Middle Third

Go Middle Third Distance = 2*Total Downward Force on Soil/(3*Earth Pressure)

Retaining Wall Righting Moment

Go Retaining Wall Righting Moment = 1.5*Overturning Moment

Overturning Moment

Go Overturning Moment = Retaining Wall Righting Moment/1.5
