TDAA, Thanks a lot for your input. Could you please explain why the flexibility of the wall will affect the extent of 3D effect?
As to the geogrid/geogrid interface shear strength, we are aware of that. Our construction specification requires 0.5 ft of separation between the grids.
what I meant by 'curving outward' is that the wall face is on the convex side of a 'L' shape. The wall is built on a 6H:1V slope and the overall stability is quite critical. Before looking into the 3D approach, I want to have a feel on how much the 3d effect may have on the slope stability...
I am analyzing the stability of a mechanically stabilized earth wall at a corner where the wall makes a 90 degree turn. The wall face curves outward. I have done the analysis using 2D limit equilibrium software (SLIDE) neglecting the 3D geometry. I have not tried any other 3D software. I wonder...
