Calculation of Dry Unit Weight
Dry unit weight (γ_d) can be calculated using the formula:
γ_d = γ_w / (1 + w), where γ_w is the unit weight of water and w is the water content.
Given: water content = 14%, unit weight (γ) = 20 kN/m3, specific gravity (G) = 2.70
γ_w = 9.81 kN/m3 (unit weight of water at standard temperature and pressure)
w = 0.14
Substituting the values in the formula, we get:
γ_d = 20 / (1 + 0.14) = 17.39 kN/m3
Therefore, the dry unit weight of the soil specimen is 17.39 kN/m3.
Calculation of Void Ratio
The void ratio (e) can be calculated using the formula:
e = (G - 1) / G
Given: specific gravity (G) = 2.70
Substituting the value in the formula, we get:
e = (2.70 - 1) / 2.70 = 0.63
Therefore, the void ratio of the soil specimen is 0.63.
Calculation of Degree of Saturation
The degree of saturation (S) can be calculated using the formula:
S = (w / w_s) x 100%, where w_s is the water content at saturation.
Given: water content = 14%, specific gravity (G) = 2.70
w_s = (G - 1) / G x 100% = 70.37%
Substituting the values in the formula, we get:
S = (0.14 / 0.7037) x 100% = 19.89%
Therefore, the degree of saturation of the soil specimen is 19.89%.
Dry unit weight (γ_d) can be calculated using the formula:
γ_d = γ_w / (1 + w), where γ_w is the unit weight of water and w is the water content.
Given: water content = 14%, unit weight (γ) = 20 kN/m3, specific gravity (G) = 2.70
γ_w = 9.81 kN/m3 (unit weight of water at standard temperature and pressure)
w = 0.14
Substituting the values in the formula, we get:
γ_d = 20 / (1 + 0.14) = 17.39 kN/m3
Therefore, the dry unit weight of the soil specimen is 17.39 kN/m3.
Calculation of Void Ratio
The void ratio (e) can be calculated using the formula:
e = (G - 1) / G
Given: specific gravity (G) = 2.70
Substituting the value in the formula, we get:
e = (2.70 - 1) / 2.70 = 0.63
Therefore, the void ratio of the soil specimen is 0.63.
Calculation of Degree of Saturation
The degree of saturation (S) can be calculated using the formula:
S = (w / w_s) x 100%, where w_s is the water content at saturation.
Given: water content = 14%, specific gravity (G) = 2.70
w_s = (G - 1) / G x 100% = 70.37%
Substituting the values in the formula, we get:
S = (0.14 / 0.7037) x 100% = 19.89%
Therefore, the degree of saturation of the soil specimen is 19.89%.
