MSE Wall Design
MSE Wall Design
(OP)
Good Day!
I am designing MSE wall for a railway project. Some parts of the railway are elevated and need MSE wall because there are roads on the sides.
How do I consider the soil reinforcements when checking for overturning, sliding? Should I consider the mse wall soil reinforcement length just like retaining wall where the vertical force from the soil on top of the heel resists the overturning & sliding moment? Or are there different parameters such as friction, etc?
I'd also like to ask for sample computations/references if you could recommend any.
Thank you very much!

Safety factors of 1.5 are typical for these modes of failure.
Global stability (something different from overturning and sliding) is related to slope stability. This is a necessary design condition.

RE: MSE Wall Design
Is it correct that I add a horizontal component from the train by multiplying it with Ka (with factors for strength 1, extreme 1, extreme 2) when checking for sliding and overturning?
I also added Pir which is the horizontal force from the inertia of mass of the reinforced soil.
RE: MSE Wall Design
Where is the railroad in proximity to the wall face? Given the huge loads involved with railroads, the analysis may be much more complicated that a simple Ka relationship.
You are looking at Pir which is a seismic factor. This could be a complicated analysis and should be looked at by someone skilled in MSE wall design.
RE: MSE Wall Design
My senior would check my design after I'm done but she has other things to check so I want to keep errors minimum. Aside from AREMA, what are other good references?
