Foundation Settlement, Sand over Silt
Foundation Settlement, Sand over Silt
(OP)
I have a project where I need to estimate settlement due to a six story structure. The general soil profile is 20 feet of medium sense sand over 80 feet of stiff silt. Best method? Thanks!

Modulus-based compression typically occurs as the load is applied. Post construction compression can be an additional 20 to 30 percent of the calculated value, depending on the design life.

It has been found quite accurate by Calif DOT, in non saturated soil but under estimates it about 50% in saturated soil.
