The appropriate design of a river diversion system during construction of dam is an essential task since dramatic consequences in view of cost and time overrun may be involved. After a short outline of the different methods of river diversion and its main ...
The Decision Aids for Tunneling are a very powerful tool in assisting decision makers. They have been developed and applied over decades. As popular as they have become in big tunneling projects, they remain complicated and less used for small tunnels. The ...
The rail link between Geneva Cornavin Station, Eaux-Vives Station and Annemasse (CEVA) is currently under construction including a cut-and-cover tunnel built by slurry walls located in the alluvium of the Foron River. The covered trench cuts the groundwate ...
Ultrahigh-performance concrete (UHPC) offers significant potential to address a variety of needs in bridge design, construction, and performance enhancement. Bridge owners have shown willingness to embrace novel solutions that could address specific challe ...
Convertir un tunnel de métro en source d'énergie géothermique, c'est la solution imaginée par des chercheurs de l'Ecole polytechnique fédérale de Lausanne (EPFL). Ils sont parvenus à quantifier les échanges de chaleur dans un tunnel et ont estimé l'économi ...
Sustained load actions are permanently present in concrete structures, as for example self-weight and dead loads on bridges or soil pressure on cut-and-cover tunnels. These actions may increase throughout a structure's lifetime, for instance after refurbis ...
This study presents a fundamental investigation of the convection heat transfer phenomenon driven by airflows in underground tunnels, with reference to the development of the so-called thermal and velocity boundary layers. The purpose of the work is to exp ...
An accurate estimation of the stress in a steel liner is required for the design of steel-lined pressure shafts, both with regard to safety assessment of ageing steel-lined waterways of hydropower plants built in the 20th century, and for new projects whic ...
The Decision Aids for Tunneling are a very powerful tool in assisting decision makers. They have been developed and applied over decades. As popular as they have become in big tunneling projects, they remain complicated and less used for small tunnels. The ...
This study is within the frame of the construction of the rail link between Geneva Cornavin station, Eaux-Vives station and Annemasse (CEVA). The project area is located at a cut-and-cover tunnel built by slurry walls located in the alluvium of the Foron R ...
