Question

Q: (TRUE) OR (FALSE):

1. A foundation built on clayey soils should always be designed using total stress parameters. ( )

2. Differential settlement causes less structural damage than total settlement.( )

3. The original bearing capacity equation was derived for plane strain conditions.( )

4. Shearing of overconsolidated clays causes negative excess pore water pressure development.( )

5. For normally consolidated clays, the angle of friction in terms of effective stresses is smaller than the angle of friction in terms of total stresses.( )

6. The shearing phase in a typical drained test is performed with the valves open and therefore excess pore water pressures generated during the test should be zero( )

7. An advantage of direct shear tests over a triaxial test is that drainage can be easily controlled with the drainage valve and therefore the strength parameters are more accurate . ( )

8. In a direct shear test, a constant vertical load is applied keeping the normal stress during the test constant, and a gradually increasing horizontal load is applied until failure ( )

9. The bearing capacity of a soil increases with the width of the foundation ( )

10. The computations of bearing capacity should be compared for every geotechnical project with full-scale load tests of the bearing capacity of the soil in situ ( )
