Induced Stress

The load applied will be equal in magnitude and opposite in direction to the actual stress on the boundary (field stress + stress redistribution due to excavation).

To add induced stress load:

1. Select the Add Induced Stress Load option from the Induced Loads sub-menu under the Loading menu.
2. In the Add Induced Stress Load dialog, define the Load Name.
3. To modify the induced stress by stages, enable the Stage Load option and select the Stage Factors button. You can apply a factor to desired stage(s).
4. Select OK to apply.

See the Tunnel Lining Design tutorial for an example of how to implement the use of an Induced Stress Load (Note: previous versions of this tutorial used a Field Stress Vector Load- the tutorial has been altered to reflect the recommended Induced Stress Load function in RS2 2019).

Induced Stress Results

After computation, the induced stress magnitude will be displayed in the RS2 Interpret program.

If only groundwater is computed (i.e., analysis is computed the Compute (Groundwater Only) option, rather than the Compute option), induced stress magnitude will not be shown.
