Is lateral squeeze the same thing as a mud wave?
I can't find any references that relate the two terms. But based on my experience, I think they are.
I personally have not been involved on a project where mud waves were induced due to fill placement. If a mud wave did develop, what is typically done to correct the issue? Is the mud wave just continually pushed out and away from the fill area? Or can the material be undercut and removed (depending upon depth and gwt)?
I'm thinking the best way to prevent it from happening would be to place your fill in thin layers and run slope stability analysis to ensure your side slopes don't fail. Then it just turns into a staged construction scenario.
I have read through the FHWA manuals where the general rule of thumb is lateral squeeze should be considered if the fill load is equal to or greater than 3 times the undrained shear strength. And is also depends on the thickness of the compressible layer of interest and the width of the sloped portion of the embankment. Are there any other references that talk more about this failure mode?
I guess I would like to hear some of your experiences with mud waves.
