Retaining Wall Design Problem 1  Determine Lateral Force by Wedge Method:

Given the proposed retaining wall below, calculate the lateral force acting on AB using the wedge method. 

1. From the retaining walls submenu open the slip plane angle calculation, SPAngle.aspx. Input the "Title" of the calculation, the "Designer/Checker" information and the variables.
Click on the "Calculate" button. Read the results. The slip plane angle is 45.466 degrees.


2.
From the retaining walls submenu open the wedge method driving wedge force calculation, DrivingWedge.aspx. Input the "Title" of the calculation, the "Designer/Checker" information and the variables.
Click on the "Calculate" button. Read the results. The total lateral resultant force is 14,248.737 lb/ft and occurs at a distance 6.667 feet from B. The overturning moment is 94,991.580 lbft.


3. Summary

The lateral force acting on AB is 14,248.737 lb/ft and occurs at a distance 6.667 feet from B. The overturning moment is 94,991.580 lbft.
