Bearing capacity of compacted ground surface Bearing capacity of compacted ground surface StructureEnggGLM (Structural) (OP) 21 May 17 14:01 What shall be the soil bearing capacity on ground surface for the layer of backfilled marl/cohesive material is compacted to 95% modified proctor density. RE: Bearing capacity of compacted ground surface oldestguy (Geotechnical) 21 May 17 16:17 While shear strength, as measured with a plate bearing test, may not result in usable bearing capacity, possible settlement probably governs. In which case consolidation tests may do the job. However marl might have some peculiar properties that these tests do not address. 95 percent Mod. Proctor is usually an indication of acceptability for density, not always bearing capacity. RE: Bearing capacity of compacted ground surface Ron (Structural) 21 May 17 23:33 Why? What is your application? "Bearing capacity" is normally associated with foundation applications; however, foundations should not be bearing at the surface for a variety of reasons. Please provide additional information.
