As part of the subsequent planning of the general project, the existing data was analysed in detail, potential for optimisation was identified, and the planning was refined. In this phase, further optimisations were identified based on different perspectives on the project. Based on a 3D subsurface model developed in advance by MA29 and the resulting geological and hydrological conditions, the tunnelling works in this section predominantly take place in Miocene strata with water-bearing sand lenses. Since one station tunnel lies entirely beneath densely built-up areas and no surface drainage was possible, an innovative tunnelling concept was developed. This concept includes a pilot tunnel constructed in advance using fibre-reinforced shotcrete. Further optimisations included both the structural design and construction logistics. In addition to optimising the station cross-sections, raising the alignment of the station structure helped reduce the life cycle costs of the structure, particularly in terms of operation and maintenance. Additionally, logistics concepts were reviewed to improve the construction process, along with approaches for material processing.","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"19 1","pages":"37-46"},"PeriodicalIF":0.0,"publicationDate":"2026-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146224562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a central infrastructure project by Wiener Linien to expand and modernise the city's U-Bahn system. The aim of the project is to expand the existing U2 station into an efficient transfer hub with the future U5 line. Particular challenges include securing the excavation pit in Vienna's heterogeneous subsoil, the proximity to existing structures and the construction work while the existing U2 line remains in operation. The construction work is being carried out with cyclical tunnelling under inner-city conditions. A central element of the construction lot is the construction of the future station structure below the existing U2 infrastructure while it is still in service, which places the highest demands on logistics, vibration protection and deformation control. The low cover to existing foundations and pipes required tunnelling with reinforced safety measures, e.g. tube umbrellas or DS injection bodies. The U2/22 ‘Rathaus’ construction lot is a technically highly complex tunnel construction project in a sensitive inner-city location. The mining construction of the tunnels in the immediate vicinity of historic buildings requires great care during tunnelling. The construction lot is a key point in the expansion of the Vienna U-Bahn system and demonstrates modern tunnel construction expertise under complex inner-city conditions.","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"19 1","pages":"47-62"},"PeriodicalIF":0.0,"publicationDate":"2026-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147269002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was constructed with a deep excavation pit in the Miocene clay silt under the effect of groundwater. The deepest part of the excavation was only about four metres above the tunnel roofs of the U-Bahn tubes. The main technical challenge was to develop a construction method that would cause as little uplift and deformation of the underground tunnels, including tracks and switches (especially curvature), as possible. A structural engineering design was developed based on comprehensive geotechnical investigations, existing documentation, condition assessments and mathematical forecasts. This design envisaged sectional excavation at depth with simultaneous construction of the above-ground floors. The aim was to keep the load caused by the excavation directly above the U-Bahn tunnels as low as possible. A comprehensive monitoring system was implemented to monitor structural deformations. During construction, the actual system behaviour largely corresponded to the forecasts. There were isolated but manageable leaks in the underground tunnels, which were successfully sealed after completion of the IKEA shell construction.","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"19 1","pages":"24-36"},"PeriodicalIF":0.0,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146224492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the factors that affect tool service life is crucial for optimising tool usage and maintenance. This practical understanding is not just theoretical, but it has real-world implications for the industry. For instance, the well-known and theorised dependence of the disc replacement on its position (centre, mid, periphery) on the TBM head can be explained simply by the different amounts of excavation work allocated to the different discs. This understanding can directly influence the design and operation of TBM machines. Apart from that, tool service life depends on the ‘sensitivity’ of the tool, which refers to the amount of metal loss tolerated without severe impairment of its efficiency. Lastly, service life depends jointly on the rock excavated and the metal employed to make the tools, which is the subject of this article. The research investigates these factors through a) a comprehensive literature review linking rock abrasivity theories with experimental studies, b) the presentation of real-life cases of TBM use in hydropower tunnel construction in Italy, and c) the analysis of real-world data on rock types, metal composition, tool consumption and machine performance. The primary objective of the present study is to identify correlations that can be used to develop a predictive model for tool durability, which will be validated using field data.","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"19 1","pages":"109-119"},"PeriodicalIF":0.0,"publicationDate":"2025-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146680443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
