For better strength and stability, the fine grained soils and coarse grained soils are compacted respectively as dry of OMC and wet of OMC wet of OMC and dry of OMC dry of OMC and dry of OMC where OMC is optimum moisture content wet of OMC and wet of OMC TRUE ANSWER : ? YOUR ANSWER : ?
Rise of water table in cohesionless soils upto ground surface reduces the net ultimate bearing capacity approximately by 30% 40% 50% 20% TRUE ANSWER : ? YOUR ANSWER : ?
If the water table rises upto ground surface, then the effective stress is reduced due to increase in pore water pressure only but total stress does not change total stress is reduced due to increase in pore water pressure only but effective stress does not change total stress is increased due to decrease in pore water pressure but effective stress does not change effective stress is reduced due to decrease in total stress only but pore water pressure does not change TRUE ANSWER : ? YOUR ANSWER : ?
