| Abstract: | Application of the Random Set Method (RSM) for stability analyses in tunnel construction. This paper discusses the application of the Random Set Method (RSM) in tunnel construction. It shows the benefits, by means of an example, of using RSM for stability analyses. The results of the calculation using state‐of‐the‐art deterministic methods are compared with the results of RSM, which cover the entire range of parameters of a homogeneous section of a tunnel. For this investigation it is postulated that the stability of a tunnel is ensured when the actual deformations correspond with the calculated deformations. If the stability analysis is made using a deterministic approach, a significant degree of interpretation is required for the evaluation and comparison of measurement and calculation results. This is not the case when using RSM because the full range of possible parameters enters the analysis as compared to selected parameter combinations. |
