What does the term "void ratio" refer to in soil mechanics?

• A. Volume of solids divided by volume of voids
• B. Volume of voids divided by volume of solids
• C. Weight of water divided by weight of soil
• D. Weight of solids divided by weight of voids

Answer: (B)

Void ratio is a critical concept in soil mechanics that defines the relationship between the volume of voids in a soil sample and the volume of solids. It is calculated by taking the volume of voids, which may contain air or water, and dividing it by the volume of the solid particles in the soil. This ratio is essential in understanding soil behavior, including its compaction, shear strength, and permeability. In practice, the void ratio helps engineers assess the porosity of the soil, which is crucial for various applications such as foundation design, slope stability analysis, and the prediction of how soil will behave under load. A higher void ratio indicates a greater volume of voids compared to solids, suggesting that the soil is less dense and potentially more compressible. Conversely, a lower void ratio signifies a denser soil with fewer voids. The other definitions provided do not accurately represent the void ratio. The volume of solids divided by the volume of voids is a different concept related to soil density, while the weight of water divided by the weight of soil and the weight of solids divided by the weight of voids do not pertain to void ratio, which focuses solely on volume rather than weight measurements. Understanding void ratio is critical for evaluating soil stability and
