Pick up the incorrect statement from the following: Compaction has no effect on the structure of a soil Permeability decreases with increase in the dry density of a compacted soil A wet side compacted soil is more compressible than a dry side compacted soil Dry side compaction soils swell more when given access to moisture 4. The maximum load carried by a pile, when it continues to sink without further increase of load, is known as ultimate bearing capacity ultimate load carrying capacity ultimate bearing resistant All 5. The compressibility of clays, is caused due to: sliping of particles to new positions of greater density bending of particles as elastic sheets expulsion of double layer water from in between the grains All 6.
