    Soil void ratio Geotechdata.info

    Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil. The posoity and the void ratio are interrelated as follows: e = n /(1n) and n = e / (1+e) The value of void ratio depends on the consistence and packing of the soil.
