This discussion is held under the viewpoint that various procedures with different results are available for the determination of such a ”safety factor“ and consequently there are also justified discrepancies between experts in the assessment of such a ”safety factor for the current state“ of the moving slope. The authors are of the opinion that the partial safety factors required by standards or former ”safety factors“ are predominantly intended for engineering structures, earthworks and dams but not generally for creeping slopes. In this case, classification of creep rate and the geological engineering assessment are always preferred. This is illustrated with two examples.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121574731","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 EWS will be implemented on the outskirts of the Bello Oriente district in Medellín. The area is characterized by an elevation of around 2,000 m, a medium slope inclination of 20° to 30° and deeply weathered crystalline rocks, which are particularly sensitive to shallow landslides during heavy precipitation. In addition to the development of a geo‐sensor network with complex data integration and real‐time evaluation, the main focus of the project is the social integration of the EWS both with the municipal authorities, which are going to take over the system after completion of the three‐year project, and with the population living in the settlement. This report describes the project and the specifications of the EWS and presents first results from the field work.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133600402","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}

For this purpose altogether 270 km of railway line between Basel and the Italian border is to be improved to a corner height of 4 m by 2020. The largest individual structure is the new Bözberg Tunnel in the canton Aargau. Various options were investigated for the preliminary design. The best variant turned out to be the new construction of a two‐track tunnel parallel to the existing tunnel. The existing two‐track Bözberg Tunnel, which is not suitable for upgrading to the 4 m standard, will be used as a service and escape tunnel. Various emergency exits lead through five cross passages from the new to the old tunnel. The short construction time of five years until opening on the one hand, and the challenging geology in the Faltenjura with swelling rock mass on the other pose great problems for client, designers, and the contractor. This article reports on these challenges and describes how they have also led to innovative solutions.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125955164","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}

One essential precondition for this is the development of high‐capacity infrastructure with modern means of transport. This includes the construction of an underground railway network, which has to be completed in a very short time due to the football World Cup taking place in Qatar in 2022. The (part) project ”Metro Green Line Underground“ was awarded in summer 2013 to a Joint Venture comprised of Porr (lead), the Saudi Binladin Group and the local construction company HBK. It includes the turnkey completion of the underground part of the Green Line in the future underground system. This includes two tunnels with a length of 17 km each, six stations, crossover structures, several emergency exits and 32 cross passages and two road underpasses. The shield drive for the running tunnels began in late summer 2014 and could be completed after only 18 months of construction time in early 2016. In addition to explaining how the simultaneous operation of six EPB machines was successfully mastered, this article also describes the conventional tunnelling of the various connection and underpass structures under inner‐city conditions.","PeriodicalId":170042,"journal":{"name":"Geomechanics and Tunnelling","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134579071","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}
