Hi All,
Our company recently received a submittal for a segmental retaining wall, that will be approximately 10-12 feet in height. Typically these submittals are pretty straight forward. However, the design engineer decided to rotate the entire wall, including the foundation base, 5 degrees back towards the retained soil on top of the 5 degree rotation he had from offsetting the blocks (see attached). Also, his calculations do not reflect this rotation properly, he is still using the equations as if the wall were vertical.
My main concern here is the global stability of the entire system. I feel that rotating the wall this way may cause the entire slope to give way. Is this thinking correct or am I way of base? Also, besides the fact that his calculations are incorrect can the wall even be constructed like what he is showing?
Also, there is no geogrid.
