CALIBRATION OF INPUT PARAMETER VALUES FOR AN ADVANCED MATERIAL MODEL OF SPRAYED CONCRETE
The paper briefly presents an advanced material model for shotcrete involving many aspects of the actual behavior of concrete. However, the contribution is focused on determination and calibration of selected input parameter values for practical use of the model in structural analysis. Two cross sec...

| description | The paper briefly presents an advanced material model for shotcrete involving many aspects of the actual behavior of concrete. However, the contribution is focused on determination and calibration of selected input parameter values for practical use of the model in structural analysis. Two cross sections of different geological conditions were chosen from a utility tunnel in Brno in order to obtain sprayed concrete samples. The laboratory tests conducted are described and then compared with results from numerical approximations. |
