Following are the results from the liquid and plastic limit tests for a soil. Liquid limit test: Plastic limit test: PL = 18.7%a. Draw the flow curve and obtain the liquid limit.b. What is the plasticity index of the soil? c. Determine the liquidity index of the soil when the in situmoisture content is 26%
A fine sand was tested in situ to give a coefficient of permeability of 3.7 x107 m/s. A sample of the same sand, 400mm high and 100 mm in diameter was then tested in a constant head permeameter. Water percolated through the soil under a head of 600mm for 5 minutes and the discharge water had a volume of 1300mm. Determine whether the in situ testing was reflected by the laboratory results and If the below water retaining structure is 140m in width, based on a coefficient of permeability of 7.8x10°m/s, determine the quantity of water that will flow through the soil and under the structure per day.
a soil sample was determined to have a water content of 8% and a degree of saturation of 42%. After adding some water, the degree of saturation was altered to 53%. take the specific gravity of the soil solids to be 2.7. assuming no change in the volume of the voids, determine the following A. void ratio B. water content% C. bulk specific gravity of the mass of the sample in the altered state.
A natural soil deposit is to be used for a geotechnical engineering project. Laboratory test results indicate that the soil possesses liquid and plastic limits of LL = 30% and PL = 22%, respectively. In addition, the sieve analysis has produced the following information: • % Passing Sieve No. 4 (4.75 mm) % Passing Sieve No. 200 (75 μm) • Coefficient of Uniformity C₁ 100% 8% 1.590 0.012 Coefficient of Curvature Co (a) Determine the soil's classification in accordance with the Unified Soil Classification System (USCS). (b) To further improve the soil's shear strength performance, the natural soil deposit (possessing an in- situ water content of w = 14%) was compacted in-situ and has achieved a saturation degree of S = 85%. If the specific gravity of soil solids is G, = 2.6, determine the soil's dry and bulk unit weights (ya and y) in its current compacted state.
Question 23 The results of a constant head permeability test for a fine sand are as follows: Diameter of the sample = 47 cm Length of sample = 57 cm Constant head difference = 29 cm Time of collection = 345 secs Weight of water collected = 429 grams Find the seepage velocity in cm/min. if the void ratio is 0.32. Round off to four decimal places.
A field sand cone test is performed on a layer of compacted fill. determined that the fill soil has a maximum dry unit weight of approximately 120 pcf. Determine the relative compaction of the compacted fill. Unit weight of dry uniform of sand: 95 pcf Weight of sand to fill the cone: 1.10 lb weight of jar + cone + sand (before test): 16.5 lb Weight of jar + cone + sand (after test): 10.5 lb Weight of moist soil excavated from hole: 6.60 lb Moisture content of soil from hole: 10 %

An undisturbed sample of fine sand is tested in the laboratory and found to have a dry mass of 4.63 kg, a total volume of 0.00198 m³ and a specific gravity of 2.70. Other laboratory tests are performed to determine the maximum and minimum density of the sand. At the maximum density, it is determined that the void ratio is 0.35 at the minimum density, the void ratio is 0.95. A. Compute the void ratio of the sand. B. Compute the relative density of the undisturbed sample. C. Compute the dry density in Mg/m³.
OMC-Proctor's Test A sample of dry sand has a volume of 1000 ml in its natural state. Its minimum volume when compacted is 750 ml. When gently poured into a measuring cylinder, its possible maximum volume is 1320 ml. what is the relative density?
