- sample saturated soil has a water content of 40%and a void ratio of 1.30 calculate density, and RD?A soil deposit has three layers having samethickness each but the permeability's ofthe layers are in the ratio of 1:2:4 fromtop to bottom. What is the ratio of averagepermeability in the horizontal direction tothat in the vertical direction?1. Classify the following soils using USCS givegroup symbol and group name.a) A 55% of soil sample retained in sieve no. 4and 89% retained on sieve no. 200. The soilsample has a liquid limit = 28% and plasticLimit = 18% Cu = 4.2, Cc = 1.4 2. A saturated soil has the followingcharacteristics:Initial Volume = 25 cm3Final Volume = 16 cm3Mass of wet soil = 45 gMass of dry soil = 31 ga) Determine the Shrinkage Limitb) Determine the Shrinkage Ratioc) Determine the Specific Gravity of the soil
- The degree of saturation of a soil is 55% and the moist unit weight is 16.66 kN/m3. When the moist unit weight increased to 17.92 kN/m3, the degree of saturation increased to 82.2%. Determine: a) Specific Gravity b) void ratio Can you please elaborate, Thankyou. What happened to that part when solving the equation 1 and 2 and how did you get the answerA soil sample taken from a borrow pit has an in situ void ratio of 1.15. The soil is to beused for a compaction project where a total of 100,000 m3 is needed in a compactedstate with the void ratio predetermined to be 0.73. Determine how much volume is tobe excavated from the borrow pit.4. Specifications require that a fill using borrow soil to be compacted at 95% of its standard proctor maximum dry density. Tests indicate that this maxi- mum is 19.5 kilo Newtons per cubic meter with 12 % moisture. The borrow material has a void ratio of 0.60. Compute the minimum dry and wet unit weight of the compacted soil, compute also the minimum volume of borrow material required to fill 1 cubic meter when compacted. Note: Assume a logical value of Gs with at least 4 significant figures.

Compute the minimum dry and wet unit weight of the compacted soil, compute also the minimum volume of borrow material required to fill 1 cubic meter when compacted. Assume a logical value of Gs with at least 4 significant figures.Undisturbed soil obtained from a test pit 0.0283 m3 (1 ft3) in volume is found to have a wet weight of 0.459 kN (103.2 lb). The dry weight of the sample is 0.376 kN (84.5 lb). What would be the effective unit weight of such a soil if it were submerged below the groundwater table? The specific gravity of the soil is determined to be 2.70.Two undisturbed soil samples, each having a volume of 0.1 ft^3, are collectedfrom different depths of the same soil layer. For sample A, located above thegroundwater table, W = 11 lb and w = 9%. Sample B is located below thegroundwater table. If Gs = 2.68, determinea. Void ratio of Ab. Degree of saturation of Ac.

- Q2/ For proposed Earth Dam fill, the soil will be compact to (95%) of standard proctor dry density. The test of borrow area indicate that (ydmax = 18 kN/m3) at optimum moisture content (11%). The soil of borrow area at natural condition has (e = 0.65) and (Gs = 2.68). Determine the minimum volume ofborrowrequired to make (600,000 m3 ) of acceptable compacted fill.A soil sample taken from a borrow pit has a natural void ratio of 1.15. The soil will be used for a highway project where a total of 100,000 m² of soil is needed in its compacted state; its compacted void ratio is 0.73. How much volume has to be excavated from the borrow pit to meet the job requirements?For a soil with a specific gravity of 2.70, prepare a chart in whichunit weight (range of 10-25kN/m3) is plotted as ordinate and voidratio (0.2-1.8) is plotted as abscissa. Plot for three percentages ofsaturation 0, 50%, and 100%.
