Longitudinal settlement trough estimation during TBM tunnelling in quaternary deposits
Year: 2025
Type: article
Abstract: The article presents the spatial issue of the settlement trough estimation above tunnel performed by the mechanized TBM EBP machine. This issue is most often modeled and analysed in the selected 2D cross-sections and spatially interpolated for the entire tunnel section along and across. The authors attempt a broader spatial analysis of monitoring data for a selected monitoring sections of a railway tunnel performed with a large-diameter TBM in a Quaternary deposits with a relatively small overburden of approximately 1D. The paper presents transverse settlement trough in selected monitoring sections and a longitudinal settlement trough above the tunnel axis. The results were analyzed as the percentage of settlements depending on the area of the origin – the front of the TBM, the shield length and the tail zone. Representative results were obtained for consolidated Quaternary deposits.
