Terzaghi bearing capacity theoy

Question 1

Properties

Answer 1

applies in strip footing
Remember that we should check settlements to see which one is governing
qallowable is MIn of qu/factorsafety and qsettlement
Also dont forget the factor of safety.

Question 2

Equation

Answer 2

qu=cNc+qoNq+0.5BGammaNgamma
We use Gamma wet in normal condition
When soil is saturated we use Gamma effective

Question 3

Modified equation

For square and circular only not for rectangular

Answer 3

For Square 
qu = 1.3c.Nc + qo Nq + 0.4BN
For circular
Modified Equations (Terzaghi)
qu = 1.3c.Nc + qo Nq + 0.3BN

Question 4

The bearing capacity factors are dependent on the friction angle, as the friction angle increases, the bearing capacity factors will also do the same which will increase bearing capacity of the soil

Answer 4

True
