Soil Classification based on Grain Distribution Analysis
D10, D30, and D60 are the diameter values of the soil particles below which 10%, 30%, and 60% of the soil grains are finer than these values respectively. Soil classification is done based on the values of D10, D30, and D60 as per the Indian Standard (IS) code.
Given D10, D30, and D60 values: 0.23mm,0.3mm, and 0.41mm respectively
Step 1: Calculate the Coefficient of Uniformity (Cu) and Coefficient of Curvature (Cc) using the following formulas:
Cu = D60/D10 = 0.41/0.23 = 1.78
Cc = (D30)²/(D10 x D60) = (0.3)²/(0.23 x 0.41) = 0.694
Step 2: Plot the values of D10, D30, and D60 on the grain size distribution curve.
Step 3: Based on the values of Cu and Cc, refer to the soil classification chart in the IS code.
For Cu > 4 and Cc > 1, the soil is classified as poorly graded (SP). Hence, the correct answer is option B.
Conclusion
The soil classification based on grain distribution analysis is done using the values of D10, D30, and D60. The coefficients of uniformity and curvature are calculated, and the soil classification chart in the IS code is referred to for determining the soil type. In this case, the soil is classified as poorly graded (SP).
