| Vv = Volume of Void | ft3 | m3 |
| Vt = Total Volume of Soil | ft3 | m3 |
| Vs = Volume of Solid Soil | ft3 | m3 |
Volume of void, abbreviated as Vv, also called void ratio,in soil refers to the volume of open spaces or pores within a soil sample. This parameter is crucial in geotechnical engineering and soil mechanics because it helps determine the soil's porosity, permeability, and compressibility.
Understanding the void ratio of soil is essential for various engineering and construction applications. It can impact the soil's ability to retain and transmit water, its compressibility under load, and its overall stability. Different types of soil (sand, clay, silt, etc.) will have different void ratios, and these properties play a significant role in the design of foundations, retaining walls, and other civil engineering projects.
