How to Calculate and Solve for Void Ratio | Soil Mechanics

Find the void ratio when the volume of void is 10 and the volume of solid is 20. This implies that; V v = Volume of Void = 10 V s = Volume of Solid = 20. e = V v / Vs e = 10 / 20 e = 0.5. Therefore, the void ratio is 0.5. Calculating the Volume of Void when the Void Ratio and the Volume of Solid is Given. V v = e x V s. Where; V v = Volume of

Examining Stone Void Space Part 1: Is 40% a Reliable Number

Stormwater detention systems often include a large portion of the storage volume within the voids of the backfill material. Depending on the underground structure design and size, allocated storage within the stone voids can vary between 25-60% of the overall storage for the project. The generally accepted number has been 40% stone void space.

How to Calculate Void Ratio

The void ratio is the ratio of the volume of voids (open spaces, i.e. air and water) in a soil to volume of solids. Where: e = Void Ratio V v = Volume of voids (m 3 or ft 3) V s = Volume of solids (m 3 or ft 3) V g = Volume of air (m 3 or ft 3) V w = Volume of water (m 3 or ft 3) The void ratio is thus a ratio which can be greater than 1.

Void ratio

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 inter-related as follows: e = n /(1-n) and n = e / (1+e) The value of void ratio depends on the consistence and packing of the soil.
