cantilever sheet piling wall penetrating a granular soil

I’ve only glanced at your file. An observation I made was that you’re using the Find command. The versions of Mathcad I’ve used require you to create a solve block by using the word “Given” above the “Find” command, with your equations to solve between the two words. Your initial guess values above the word “Given”. Are you setting up the solve block correctly?

Those boxes are not decorations; they're Mathcad Prime solve blocks, which is why some of the equal signs appear bolded.

OP, posting the actual Mathcad file is much more useful; a non-executable PDF does not do much for debugging. The box is the equivalent of "Given"; a closer examination shows the first section to be "Guess Values, 2nd section "Constraints", 3rd section is "Solve", I think.

Hi IRstuff,

I tried solving it using soil pressures rather than soil net pressures used in the example.

I meant the way in the attached image:

Hi all,
Are there any thoughts?

I never design walls using net soil pressure. I put the driving forces on one side of the wall and the resisting forces on the opposite side. It is easier to visualize, calculate, check, and eliminates un-needed computations.
