Good morning-
I have a question regarding soldier pile design.
In the 17th Ed of AASHTO (ASD) Fig 5.6.2A provides an equation for active earth pressure below the dredge line with a factor of 1.5.
In the LRFD Code (Fig. 3.11.5.6-1), the 1.5 has been replaced with a factor of 0.5 for this equation.
In both codes a factor of 1.5 is applied to the passive earth pressure below the dredge line.
Here are my two questions:
1. Which ACTIVE earth pressure equation is correct? The 1.5 version or 0.5?
2. Where did this earth pressure distribution come from?
Thank you for any insight you may provide.
