A 1 m wide continuous footing is designed to support an axial column load of 250 kN per meter of wall length. The footing is placed 0.5 m into a soil with a cohesion of 25 kPa and an angle of internal friction of 5°. Most nearly, what is the value of the Terzaghi bearing capacity factor, N?(A) 0.5(B) 1.1(C) 1.6(D) 7.3

correct option is (A) 0.5

Explanation:

given data

axial column load = 250 kN per meter

footing placed =  0.5 m

cohesion = 25 kPa

internal friction angle =  5°

solution

we know angle of internal friction is 5° that is near to 0°

so it means the soil is almost cohesive soil.

and for  a pure cohesive soil

= 0

and we know formula for is

= (Nq - 1 ) × tan(Ф)   ..................1

so here Ф is very less   should be nearest to zero

and its value can be 0.5

so correct option is (A) 0.5

oil flow is a highly convective flow compared to water flow at normal temperature and pressure.
