When vibrating soil for compaction, what are the practical limits for influence?

Is the value provided by a shear vane test corrolate to the ucs value? If so, how?

What do you soils/civil guys use to design retaining walls when sand/silt is placed behind as water based slurry (say at about 60 to 75% solids)? Using pure hydrostatic head is always way too high. What if the wall is permeable? sorry, a lot of questions here.
