Question Paper
1. Compute the intensities of active and passive earth pressure at a depth of 8 metres in dry cohesionless sand with an angle of internal friction-of 30° and unit weight of 18 kN/m^3. What will be the intensities of active and passive earth pressure, if the water level rises to the ground level Take saturated unit weight of sand as 22kN/m^3.
2. Discuss the following:
Seismic refraction method
Electrical resistivity method
When do you recommend the use of these tests in practice?
3. Distinguish between shallow and deep foundations. Explain the advantages and limitations of various types of foundations.
4. What are the objectives of analysis of pile group? State the principle of group action used for this analysis.
5. A strip footing, 1 m wide at its base is located at a depth of 0·8 m below the ground surface. The properties of the foundation soils are y 18 c 30 kN/m^2 and 20°. Determine the safe bearing capacity, using a factor of safety of 3. Use Terzaghi's analysis. Assume that the soil fails by local shear. For =11·8, Nq, =3·9 and =1·7.
Explain the functions of foundation.
Discuss the requisites of satisfactory foundations.
7. Explain the Coulomb's and Rankine's earth pressure theories in detail.
8. Discuss different methods of site investigation and soil exploration.
9. Calculate the factor of safety with respect to cohesion of a clay slope laid at 1 in 2 to a height of 10 if the angle of internal friction is cjl c =25 kN/m^2 and y =19 kN/m^3. What will be the critical height of the slope in this soil?
10. Write short notes on any two the following:
Raft Foundation
Floating Foundation
Floating Caissons
