Void ratio - Geotechdata.info

27 行· 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. It is directly affacted by compaction. Some typical values of void ratio for ...
