Hello
I am in the process of designing a soldier pile wall for an access road. The max height of the wall is 12 feet and the SGR recommends drilled soldier pile walls as the best alternative. I have not designed a soldier pile wall before and needed help with how to get started. I am starting off using the AASHTO LRFD Chapter 11.8 for Non-Gravity Cantilever Wall design.
The SGR notes that the soils are dense to very dense sand, with bedrock 15 feet below finished grade of the access road (26 feet from the top of wall). There is also a soil layer of silty loam at the top 5 feet, so I will have to use multiple different values of "Ka" to get the soil pressures. The wall will also have a 250 psf live load surcharge on it, with a 1:2.5 (V:H) slope behind it.
Can you please help me with any insight and or design examples that I can follow?
Thank you.
