Basic MSE Wall Question
Basic MSE Wall Question
(OP)
Greetings,
I just had a simple question that I was hoping to get an answer to. I'm in a situation where I am required to excavate 20ft below an at-grade railroad bridge with an ~8 lane road totalling 144 feet in width. I will need to build some sort of retaining structure to hold this soil back. I know that MSE walls are not desirable in cut situations, but boring tests have shown that the soil being excavated is suitable fill material for MSE Wall. In this case, would it still be feasible to construct an MSE wall in this location, or should I stick to somnething like a retaining wall? Thanks for any help.

Anyway,typically if you are going to excavate that deep close to a structure, you will need a support system in place prior to excavation. A cantilever wall can only be constructed after excavation is performed. A solder-pile with tie-back or, secant pile wall are all possible, but with limited data, it is difficult to make a better recommendation.
