I am not an engineer (I'm a geologist) but need some advice/information from professional engineers regarding the compaction of soils with an increase in depth. It would appear to be, that a soil (granular or cohesive) would increase in density with an increase in depth due to the load of the overlying soil even if initially deposited in a less compacted state. This appears clear to me from preloading projects I have been involved with. But I am looking beyond a preloading depth (>20 feet). Is there any research information that shows this to be true or am I incorrect about this.
I deal with sinkholes in Florida so a portion of the sinkhole/karst phenomena is the decline in density at depth.
Thanks in advance
