Permeability of Soils

Permeability is a measure of the ability of a soil to transmit water or other fluids through it. It is an important property in civil engineering, as it affects the drainage characteristics and stability of soil.

Particle Size Distribution

The permeability of a soil is influenced by its particle size distribution. The particle size distribution curve provides information about the relative proportions of different particle sizes in the soil. The D10 value represents the particle size at which 10% of the particles are smaller, and 90% are larger.

Relationship Between D10 and Permeability

There is a general relationship between particle size and permeability. As the particle size decreases, the permeability tends to increase. Smaller particles have more void spaces and a higher surface area, allowing water to flow more easily.

Calculating the Ratio of Permeabilities

In this question, we are given two soils with D10 values of 0.6 mm and 0.3 mm. To calculate the ratio of their permeabilities, we can use the following formula:

Permeability ratio = (D10 of Soil 1 / D10 of Soil 2)^2

Using this formula, we can substitute the given values:

Permeability ratio = (0.6 mm / 0.3 mm)^2
= (2)^2
= 4

Therefore, the approximate ratio of the permeabilities of the two soils is 4. This corresponds to option 'A' as the correct answer.

Conclusion

The permeability of a soil is influenced by its particle size distribution. Smaller particles tend to have higher permeabilities. In this question, we used the D10 values of two soils to approximate their permeability ratio, which was found to be 4. Understanding the relationship between particle size and permeability is essential in civil engineering for designing drainage systems and assessing the stability of soils.
