Soil Mechanics and Foundation If the water table rises upto ground surface, then the effective stress is reduced due to decrease in total stress only but pore water pressure 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 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 effective stress is reduced due to decrease in total stress only but pore water pressure 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 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 ANSWER DOWNLOAD EXAMIANS APP
Soil Mechanics and Foundation A retaining wall 6m high supports a backfill with a surcharge angle of 10°. The back of the wall is inclined to the vertical at a positive batter angle of 5°. If the angle of wall friction is 7°, then the resultant active earth pressure will act at a distance of 2 m above the base and inclined to the horizontal at an angle of 12° 17° 7° 10° 12° 17° 7° 10° ANSWER DOWNLOAD EXAMIANS APP
Soil Mechanics and Foundation In the triaxial compression test, the application of additional axial stress (i.e. deviator stress) on the soil specimen produces shear stress on horizontal plane only vertical plane only all planes except horizontal and vertical planes both horizontal and vertical planes horizontal plane only vertical plane only all planes except horizontal and vertical planes both horizontal and vertical planes ANSWER DOWNLOAD EXAMIANS APP
