This document provides laboratory test methods for the determination of the coefficient of permeability of soils within the international field of geotechnical engineering.
The tests have not previously been standardized internationally. It is intended that this document presents broad good practice and significant differences with national documents is not anticipated. It is based on international practice.
The permeability test is carried out on a cylindrical test specimen that is either confined laterally by a rigid container or by a flexible membrane. The specimen is subjected to differential hydraulic head and the water flow is measured under either a constant or falling head. The results are used to determine the coefficient of permeability of the soil specimen. Tests can be carried out on undisturbed, remoulded, compacted or reconstituted specimens.
The calculation of the coefficient of permeability assumes the application of Darcy’s law for laminar flow of water under saturated conditions.
It is possible that the size of the specimen does not adequately represent the fabric features present in field conditions.
