Surcharge Pressure

[SOFLENG]

I am designing a continuous deadman anchor for a sheet pile bulkhead. There is a 20' high MSE wall embankment 37' inboard of my anchor wall. I do not believe the embankment is influencing the anchor wall (pushing in the wrong direction) but I need to proove it. Using classical strip load analysis, I still wind up with 350 psf at the bottom of the anchor 10' down. Any thoughts on how to analyze this?

Probably a method would be graphically. First substitute the MSE wall by a surcharge in the horizontal surface at the left of its base. Forget for a moment you are in an anchor application, and find what the critical active wedge would be for that situation, hence its limi surface. Then ascertain if your anchor is soundly beyond the critical surface.

I include a Mathcad 2000 worksheet for a simpler case of horizontal surface.

I don't really understand the geometry. I sketch would help, unless ishvaaag answered your question.
