cuvy mevcupage Course code: CE 1115 Term Paper 1. Introduction. 2. 3. 4. Objectives and applications of “Permeability and Seepage". Illustrate flow net. State the application and properties flow net. Briefly describe the seepage pressure and quick condition. For a homogeneous earth dam of 70 m high and 2.3 m free board, a flow net was constructed and following results were obtained- No. of potential drop = 25 No. of flow channel = 7 The dam has a horizontal filter of 42 m length at its downstream end. Calculate the discharge of the dam in m/s, if the coefficient of permeability of the dam material is 3.5 x 10 cm/sec. Describe permeability. Show the expression for determination of coefficient of permeability for falling head test method. Water is flowing at the rate of 0.045 ml/sec in an upward direction through a sandy soil whose coefficient of permeability is 2.8 x 103 cm/sec. The sample thickness is 12 cm and cross-sectional area is 55 cm. Find the effective pressure at the middle and bottom section of the sample, if the saturated unit weight of the sample is 19.5 KN/m?. To find the coefficient of permeability for a clay soil the permeability test was carried out in a variable head permeameter having the diameter of the sample container to be 10 cm. The initial head of water in the stand was found to be 50 cm and it was observed to drop 32 cm in 3.50 minute. If the sample be 15 cm high and the diameter of the standpipe be 1.7 cm then determine the coefficient of permeability of the clay in meter/day. 6. 8 8. 9. A soil sample has the following properties: LL = 55%, PL = 21%. SL = 15%, w=38%. Calculate the consistency index. 10. 11. Determine the maximum possible void ratio for a uniformly graded sand of perfectly spherical grains. Show the expression for determination of coefficient of permeability for falling head test method. A soil sample has a porosity of 75 % and the specific gravity of 2.65. 12.
