The use of vane shear tests in granular materials for shear strength measurement
The use of vane shear tests in granular materials for shear strength measurement
The field vane shear test offers a convenient way for assessing the undrained shear strength of fine soils. However, various factors, including the rotation rate, vane insertion disturbances, vane shape, soils’ organic content and strength anisotropy, can affect the test results. Its application is largely limited to clays, and its suitability for other granular materials like tailings is questionable. Nonetheless, due to its simplicity and ease of use, ongoing theoretical developments and increased data reporting for other granular materials have become available. In the author's opinion, reviewing and summarising recent developments in the vane shear test for granular materials can help interested readers to find out the relevant papers on a specific topic and aid engineers in interpreting the available measured results.
