UAEU CIVL 340: Soil Mechanics TUTORIAL 3 1. A constant head permeability test was conducted on a cylindrical soil sample with a diameter of 18.0 cm. Two piezometers were attached to the permeameter. The elevation of water in the upper piezometer was 181.0 cm, and the elevation of water in the lower piezometer was 116.6 cm. The tips of the piezometers were spaced 16.7 cm centre to centre. Under steady state condition, 3 892 cm of water was collected in 112 seconds. Determine the permeability of the soil. 2. For the two sand columns in Figure Q2, determine the pressure, elevation and total head at point A of the sample. XXXXXXXXXXFigure Q2 (….continued on next page)3. An underlined irrigation canal is aligned parallel to a river, as shown in Figure Q3. This cross- section continues for 2.5 km. The soils are generally clays, but a 150 mm thick sand seam is -2 present as shown. This sand has k = 9 ? 10 cm/s. Compute the water loss from the canal to the river due to seepage through this sand layer. El. 57 m El. 37 m 150 m Figure Q4 4. 5.Figure Q5 6. 7. 7
