What formula represents the degree of saturation in soil?

The degree of saturation in soil is a crucial concept in geotechnical engineering, as it indicates the amount of water present in the soil compared to the soil's voids. The correct formula for calculating the degree of saturation is the volume of water in the voids divided by the volume of voids multiplied by 100. In this context, the degree of saturation (S) can be expressed mathematically as: \[ S = \frac{V_w}{V_v} \times 100 \] where \( V_w \) is the volume of water in the soil, and \( V_v \) is the volume of voids in the soil. The resulting percentage indicates how saturated the voids are with water. Understanding this relationship is crucial because a fully saturated soil has a degree of saturation of 100%, meaning all voids are filled with water. Conversely, unsaturated soils have a degree of saturation less than 100%, affecting their mechanical properties, effective stress, and behavior under loading conditions. The choice made illustrates this principle correctly, emphasizing the significance of recognizing the appropriate relationship between water volume and void volume in determining the saturation state of the soil. The other options do not accurately define the degree of saturation, focusing instead on different volum

The correct formula for calculating the degree of saturation is the volume of water in the voids divided by the volume of voids multiplied by 100.

In this context, the degree of saturation (S) can be expressed mathematically as:

[ S = \frac{V_w}{V_v} \times 100 ]

where ( V_w ) is the volume of water in the soil, and ( V_v ) is the volume of voids in the soil. The resulting percentage indicates how saturated the voids are with water.

Understanding this relationship is crucial because a fully saturated soil has a degree of saturation of 100%, meaning all voids are filled with water. Conversely, unsaturated soils have a degree of saturation less than 100%, affecting their mechanical properties, effective stress, and behavior under loading conditions.
