The major applications for fibres are for the reinforcement of sprayed concrete and pre‐cast concrete segmental linings, but fibre reinforcement is also increasingly used for other applications such as trackbed/trackslab and minor precast concrete elements such as cable ducts, drip shields, and drainage elements. As the technology has matured, a wide variety of fibre types, made from different materials, has emerged. Standards have been developed for the manufacture, testing and application of all these fibre types. Moreover, design guidelines and codes have been published and new design methods are still being developed. The International Tunnelling Association has published several guidance documents in this field. Last but not least, FRC has an important role to play in reducing the carbon footprint of tunnelling projects.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117624671","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}

Due to the exposed location in the high mountains, mixing plants were installed on both portal sides for the concrete supply; the concrete aggregate was largely produced from the excavated material, with a gravel plant being built in Preda for this purpose. The planned tunnel lining provides for a single‐shell shotcrete construction for the most part. In the course of the excavation work, the excavation support was optimised so that the reinforcement mesh in the main support class in the single‐shell area were replaced by steel fibre shotcrete.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"11 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120030684","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}

A key objective for the design was the optimization of the tunnel shapes and the advanced simulation of the fibre reinforced shotcrete properties, to allow these openings in the initial tunnel linings to be achieved without conventional bar reinforcement or thickenings, thus simplifying and accelerating the construction, whilst reducing health and safety risks.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"693 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"119796699","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}

{"title":"BIM‐Anwendungsfall (AwF) Abrechnung‐Vortrieb am Beispiel des Zentrums am Berg","authors":"Robert Wenighofer, Johann Waldhart, Nina Eder, Katharina Zach","doi":"10.1002/geot.201900079","DOIUrl":"https://doi.org/10.1002/geot.201900079","url":null,"abstract":"BIM modelling of infrastructure works is controlled by a global market consisting of few software suppliers and is contingent upon the functions provided by them. Customization options furnished by the software suppliers often enable enhancement of functions, which is essential for infrastructure BIM although not completely available. This enables improved interoperability of the software tools used in this area. IFC is most likely to become an established international format for data exchange with its constant but also intricate further development. However, in underground infrastructure construction, both international and national standards are used and the integration of the latter in IFC cannot be anticipated. Hence, the implementation of BIM has to apply national standards in the use cases of collaborative data exchange among the different disciplines in tunnelling. In this contribution, the use case of payment of excavation classes and its implementation in a BIM environment are addressed. It discusses the interoperable interlinkage of software tools commonly used in construction to generate consistent digital data transfer and it underscores the need for an interdisciplinary agreement to integrate national standards into adequate practice for the implementation of BIM.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130741060","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}
