What is BS 1377-6 – soil permeability tests and pore pressure measurement about?
Soil testing is a very important part of building and road construction projects. BS 1377-6 discusses methods of testing for soil for civil engineering purposes.
BS 1377-6 is the sixth part of the multi-series, and specifies methods of test for the determination of consolidation and permeability characteristics of saturated soils using apparatus which is more complex than that used for the tests described in BS 1377-5.
Who is BS 1377-6 – soil permeability tests and pore pressure measurement for?
BS 1377-6 on soil permeability tests and pore pressure measurement is useful for:
- The construction industry
- Civil engineers
- Ground engineering consultants
- Construction contractors and clients
- Ground investigation specifiers
- Geotechnical advisers
- Geotechnical soils testing laboratories, managers, and technicians
- Local authority engineers and planners
- Infrastructure managers and planners
Why should you use BS 1377-6 – soil permeability tests and pore pressure measurement?
Soil permeability, in terms of a permeability coefficient (k), measures a soil's ability to allow water to pass through it. Soils are permeable materials due to their grain structure and the existence of interconnected voids.
BS 1377-6 walks you through the procedures by providing you with details such as apparatus, preparation of specimens, cell assembly, preparation of test specimen, test procedures, calculation, and reporting results of soils.
Two types of equipment are used:
- Hydraulically loaded one-dimensional consolidation cell
- A triaxial consolidation cell
The most significant capabilities of both types of apparatus are:
- Measurement of pore water pressure
- Control of drainage
- Application of backpressure to the specimen.
Consolidation or triaxial cells of large diameter enable large specimens to be tested so that some account can be taken for the effects of the soil fabric. These procedures appear for the first time in BS 1377-6.
Reference should be made to BS 1377-1 for general requirements that are relevant to all parts of BS 1377-6, and for methods of preparation of soil and specimens for testing.
BS 1377-6 on the test for soils for civil engineering purposes, increases the efficiency of the project.
BS 1377-6 assists you in demonstrating better and more cost-effective soil management strategies for reducing the possibility of foundation issues, and determining the best building options to use.
