Heave analysis on "I" wall

Heave analysis on "I" wall

Heave analysis on "I" wall

(OP)
I am analyzing an "I" wall with sheet pile material and a berm on one side to be used as flood protection.  The elevation of the berm on the protected side is 4', the top of the elevation of the sheet pile is 10 ft. The assumed elevation of the water on the flood side is also 10 ft.  The depth of the sheet pile is approximately 35 ft.  I have performed an overall stability analysis and also a local stability on the sheet pile.  In addition, I have evaluated seepage.  All is OK.

Question: does it make sense to evaluate "heaving"?  I'm under the impression that heaving is really only a problem with excavations (i.e. trenches).

Any thoughts appreciated.

RE: Heave analysis on "I" wall

Thanks for the response and the link.

The berm is continuous on the protected side.  There is no berm on the flood side.  I was asked to look at heave, but I don't think that it is an applicable mode of failure.  I assume that the water on the flood side would be causing the "heave" on the protected side, but that is what the global stability analysis is checking for (figure 5-1 in EM 1110-2-2504).  I think it is simply a semantics issue, but I was just trying to make sure I wasn't overlooking something.
