Question Paper
Explain active and passive earth pressures in the design of retaining walls and sheet piles.
A retaining wall, 10 m high, retains a cohesionless soil having an angle of internal friction of 30° The surface of the soil is level with the top of the wall. The top 3 m of the fill has a unit weight of 20 kN/m^3 and that of the rest is 30 kN/m^3 . Sketch the earth pressure diagram under active state.
Why is soil investigation and exploration necessary for a construction project
Explain and discuss the various factors that are considered in deciding the number and depth of bore-holes required for subsoil exploration.
Discuss vane shear test.
Determine the depth at which a circular footing of 2 m diameter has to be founded to provide a factor of safety of 3 if it has to carry a safe load of 2000 kN. The foundation soil has c =10 kN/m^2 y 18 kN/m^3. Use Terzaghi's analysis. Nc =37.2, Nq =22.5 and Ny =19·7.
Why do we go for combined or continuous type of foundations, particularly when the structure is on property line?
Explain the design consideration of open well foundations.
Explain different types of settlement and its causes. Explain their limitations.
Explain LS. methods to find the bearing capacity of piles.
6. A group of 16 piles of 500 mm diameter is arranged in a square pattern with centre to centre spacing of 1·25 m. The piles are 16 m long and are embeded in soft clay with cohesion of 20 kN/m^2. Bearing resistance may be neglected for piles. Adhesion factor is 0.7. Determine the load carrying capacity of the pile group.
7. Write short notes on any four of the following:
Soil Samplers
Floating Foundation
Plate Load Test
Rankine's Theory of Earth Pressure
Negative Skin Friction
Stabilization of Soil
