Soil Classification
Classification of soils, according to Robertson (1986 or 2010) allows us to specify soil behavior type (SBT) and other parameters directly from the results of CPT - then input parameters of soils it's not necessary to input. We recommend to check generated soil parameters before the calculation.
In the "Soil classification" frame test for classification is selected (defined in the "CPT" frame). Classification of soils is performed according to Robertson (1986 or 2010).
This frame serves to input penetrometer net area ratio α [-].
The unit weight of soil γ is possible to input with the same value for all layers of soils or it's calculated automatically from the results of CPT (for each layer separately). The frame serves to input a minimum thickness of the layer of soil h. It affects the distribution and number of individual layers of soil in the geological profile of solved task.
By checking the option "Insert the results of classification into a geological profile automatically" the generated geological profile assigns to the analysis automatically.
