Response of a rock mass to circular excavation (non-uniform in-situ stress)
25 February 2016
In the video, we show how to set-up the model discussed in the validation report below. The validation concerns the response of a rock mass due to circular excavation in a Hoek-Brown material with non-uniform in-situ stress. The initial calculation is performed with the Field stress calculation type available since 2D 2016.
Since PLAXIS CONNECT Edition V20, it is possible to define a local field stress condition in each soil polygon (cluster). To do so, in Soil mode, right-click the soil polygon and in the context menu choose Soil_n > Create > Create field stress. Selecting this option displays ClusterFieldStress in the selection explorer, which can be set in Staged construction.
