AS 1289.6.2.2:2020 PDF
This Standard sets out a method for determining the effective shear strength of dry, fine-grained and clay soils by direct shearing in a shear box having shear plane dimensions up to a maximum of 300 mm × 300 mm. The method specified is for a single-staged test, i.e. with a single value of applied normal stress.
This Standard was prepared by Standards Australia Committee CE-009, Testing of Soils for Engineering Purposes, to supersede AS 1289.6.2.2—1998.
The objective of this document is to set out a method for performing direct shear (shear box) tests on soils with a wide range of particle sizes. The data recorded from the test method is used to interpret soil strength. Usually three single-stage tests at different normal stresses are applied. The interpretation of the results may then be carried out by a suitably experienced and qualified person, such as a geotechnical engineer.
