A.
When water table is above the base of a footing, the dry weight m should be used for soil below water table |
|
B.
When water table is located somewhat below the base of a footing, the elastic wedge is partly of moist soil and partly of submerged soil, and a suitable reduction factor is used |
|
C.
When water table is just at the base of the footing, no reduction factor is used |
|
D.
None of these. |
|
A.
In soils, the flow index indicates variation in shear strength with water content |
|
B.
Liquid limit minus plastic limit, is known as plasticity index of the soil |
|
