Traditional generation of simulation models largely depends on tunnel design and reports, which are error prone due to the involvement of manual intervention. This article presents the application of a digital workflow to efficiently transfer automatically acquired data from tunnel projects to computational simulations. The application workflow is developed and executed through a web-based environment. Project data from the Victory Boogie Woogie tunnel is retrieved from the process controlling software PROCON via web services to generate numerical simulations for settlement predictions at different tunnel sections. The simulated results are validated using real measured settlements in the project to prove the quality of the simulation model. Different scenarios of applying operational steering parameters are then investigated, utilising the simulation model, which can be used to support the on-site engineers as an assistance system to drive the tunnel boring machines. The work has been carried out within the framework of the transfer project T2 of the Collaborative Research Center “Interaction Modeling in Mechanized Tunneling” (SFB 837), which aims to implement and test a digital twin for process control under practical conditions in the tunnelling industry.","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"17 4","pages":"324-331"},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141358405","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}

Since 2011, several concessionaires, contractors and designers were involved. In June 2016, a major failure occurred at a high cut slope of the right bank (RB) valley flank. In 2017, contractor Limak took over the project with a US$ 600 mio concession contract. To secure the contractual agreement for state-guaranteed energy remuneration, Cetin Dam and hydro hydroelectric power plant (HEPP) had to be operative in 2020. Missing the time target would have implied high economic losses for the concessionaire, and this set-in-stone deadline imposed extraordinary pressure for developing fast and reliable solutions. Worryingly, progressing failure became evident at the failed RB cut slope, while rehabilitation works were ongoing. In late December 2017, shortly after a review of geotechnical conditions and slope design for the troubled RB slope had started, also parts of the left bank (LB) cut slope failed below crest level and threatened to grow into a global slope failure. With only 26 months’ time left for starting energy production, the slope instabilities jeopardised the economic success of the entire project. Within a 3-month emergency mission for both RB and LB slopes, a dedicated team succeeded in understanding the geotechnical problems, planning and implementing immediate mitigation measures, and developing design solutions. Operation of Cetin Dam and HEPP commenced in 2020.","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"17 3","pages":"184-194"},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141016048","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 contribution shares experiences and challenges from the static and seismic design of embankment dam structures and ground treatment options. Finite element-based static and seismic analyses using the Hardening Soil Small Strain model (HSS) showed that preconsolidation has clear benefits compared to stone columns for ground improvement purposes. Regardless of general advantages of surface sealing systems for frequent and rapid impoundment level changes, it was found that clay core design options perform very well under seismic loading conditions and even better than surface-sealed structures. Seismic ground and structure response analyses involving soft soil considering shear strain-dependent stiffness degradation revealed that deamplification is expected in contrast to the rule-of-thumb amplification approaches enshrined in many seismic design guidelines and codes. It was found that this effect increases with seismic magnitudes and that saturation of peak ground acceleration (PGA) takes place. This results in relatively moderate structure excitations even under significant dynamic excitation.","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"17 3","pages":"212-219"},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140664608","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}
