Allowable settlement often dictates the allowable bearing pressure rather than soil bearing capcity. Site investigation needed! Without knowing soil conditions I would not use anything higher than 1500 psf for a first cut. On problem with soils they can vary widely within a given area. For...
Will a Rotosonic Drill rig consolidate soil in advance of the bit? I have a project were split spoon samples were collected on a rotosonic drill rig in non-cohesive saturated sand. The density obtained from these samples seemed high in my opinion. Knowing that you can vibro-compact sand I am...
The test is to determine Dynamic Shear Modulus of Soil (G). I am also interested in other test methods to determine G and material damping ratio of soil if any body has suggestions.
I would be wary of an averaged value unless the soil types are the same for the average. CBR tests are reasonbly cheap, I would run a couple for piece of mind. msucog has a very valid point.
