This study also shows that the RET has strong promise as a new tool for testing undrained shear strength of fine-grained soils. DataFit is a tool for performing curve fitting, statistical analysis & data plotting.

The results were validated by the RET, which was proven to take into account soil plasticity with a reliable degree of accuracy. In comparison with the result obatined using the Bjerrum's correction factor, the undrained shear strength was better represented when s u values were correlated with the liquidity index. The effect of soil plasticity on undrained shear strength was examined using the liquidity index instead of Bjerrum's correction factor.

Software DataFit 8.0.32 (Oakdale Engineering, Oakdale, PA, EUA) was used for. School of Mechanical and Aerospace Engineering, Nanyang Technological University. Atterberg limits test, miniature VST, and reverse extrusion test (RET) were conducted on 120 remolded samples. Nine models were adjusted, and the best equation (local) was compared to. This study aims to reevaluate the Bjerrum's correction factor in consideration of a different approach and a relatively new method of testing. The vane shear test (VST) technique that is less sensitive to sample disturbance involves a correction factor against the soil plasticity, commonly known as the Bjerrum's correction factor, μ. The unconfined compression test (UCT) is widely used in laboratory to measure this parameter due to its simplicity however, it is severely affected by sample disturbance.

You can choose from more than 600 pre-defined equations, which are commonly used in statistical, scientific and engineering applications, or create your own equations. The undrained shear strength ( s u) of fine-grained soils that can be measured in situ and in laboratory is one of the key geotechnical parameters. With DataFit, you can perform linear or nonlinear regression on data containing up to 20 independent variables.
