1a You are appointed as site engineer and have been tasked to carry out site investigations for an earth dam construction site. Describe the investigation procedure and discuss what information is required for the preparation and presentation of the report.

1b A standard penetration test was carried out at a site. The soil profile is given in figure 1(b) below with the penetration values. The average soil data are given for each layer. Compute the corrected values of Nand plot showing the variation of observed and corrected values with depth.

1c The unit weight of a soil of a 30° slope is 17.5kN/m3. The shear parameters c and ? for the soil are 10 kN/m2 and 20° respectively. Given that the height of the slope is 12 m and the stability number obtained from the charts for the given slope and angle of internal friction is 0.025, compute the factor of safety.

2a For the retaining wall shown in figure 2(a), draw the active earth pressure distribution diagram and obtain total active force on the wall.

2b A retaining wall 4.5 m high with a vertical back supports a horizontal fill weighing 18.60 kN/m3 and having ? = 32°, d = 20°, and c = 0. Determine the total active thrust on the wall by Culmann’s graphical method.

3a A canal having side slope 1:1 is proposed to be constructed in cohesive soils to a depth of 4.5m below the ground surface. The soil properties are a given below; ?u=15?, cu=10kN/m2. e=1.0 G=2.65. find the factor of safety with respect to cohesion against failure of bank slopes;
i) When the canal is full of water and.
ii) When there is sudden draw down of water in canal.

3b Determine the depth at which a circular footing 2m diameter be founded to provide a factor of safety of 3.0. If it has to carry a safe load of 1500 kN. The foundation soil has c=15 kN/m2, ?=30? and unit weight of soil ?=18kN/m3.

3c A large scale bearing capacity test on a footing of size 1.05mX1.05m at a depth of 1.5m yielded an ultimate value of 141 kN. Unconfined compressive tests on the soft saturated clay yielded a strength of 0.03 N/mm2. If the unit weight of the soil is 16 kN/m3, how much does the test value differ from that obtained using Terzaghi’s bearing capacity equation?

4a Design a pile foundation system in 20 m thick soft clay with undrained cohesion of 60kPa, density of 18kN/m3 and water content of 30%. The clay layer is underlined by hard rock. The pile foundation should carry a load of 6500 kN. Take liquid limit=60%, G=2.7.

The initial void ratio of clay is 1.0 its saturated unit weight is 20 kN/m3 and its liquid limit is 50%. The ground water table is at the top of the clay layer. A square footing 2m x 2m is founded at a depth of 1.0 m below the GL at the site. The load on the footing is 1200 kN. Calculate the settlement of footing due to consolidation of the clay layer.
