Reducing the monotonous design in the worlds deepest and longest sub-sea road tunnel Rogfast, Norway
Published in Daniele Peila, Giulia Viggiani, Tarcisio Celestino, Tunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art, 2020
E39 Rogfast is a subsea tunnel that will pass below Boknafjorden in the south west of Norway between Harestad and Laupland, with a separate tunnel to the island Kvitsøy. The tunnel will become the worlds longest and deepest subsea road tunnel with a length of 26,7 km and its deepest point at approximately 392 meters below sea level. The 4 km long tunnel to Kvitsøy is connected by a two-level interchange at a depth of around 260 meters. E39 Rogfast is the first project to be constructed in the larger ambition to get a ferry-free highway along the European route E39 from Trondheim to Kristiansand. Upon completion the travel time between Stavanger and Bergen will be reduced by 40 minutes (StatensVegvesen, 2018). See Table 1 and Figure 1 for more information.

Many research results were obtained on land tunnel site selection before subsea tunnels appeared. The land tunnel projects are developed for long, large span and deep-depth burial cases. Inevitably, the tunnels pass through areas with unfavorable geology, such as great depths, high stresses, soft rocks, faults, and karst. Therefore, the study of the site selection of tunnels has great engineering significance. Due to the particularity of the subsea tunnel project, the basic parameters and construction conditions of the subsea tunnels are different. Designing a scientific and effective evaluation method for the subsea tunnel site selection is essential. There are few studies on the site selection of subsea tunnels. Wang (2013) established a new tunnel entrance stability evaluation method based on the GIS (Geographic Information System) method. The method has been tested to have good accuracy of tunnel entrance location. Wu et al. (2016) compared the construction time in built and super cross-sea engineering understudies. The authors also discussed the critical technology problems in applying submerged floating tunnels to Qiongzhou Strait from crossing way and structure plan. Hilmola, Lorentz, and Rhoades (2015) analyzed the potential change using data envelopment analysis on the existing alternative transportation chain in the Helsinki (Finland)−Tallinn (Estonia) short sea route. The study also included the planned railway tunnel between the two cities. Borg, Bjelland, and Njå (2014) discussed the capability of the Bayesian Network (BN) model-TRANSIT for quantitative risk assessment of road tunnels. The authors also found that the model has severe limitations, especially for novel tunnel design projects such as the Rogfast. Bjelland and Aven (2013) reviewed and discussed the use of risk assessment in designing the longest and deepest subsea road tunnel in the world, the Rogfast. Pliego (2005) outlined the Gibraltar Strait Tunnel study process. They elaborated on the project background, basic alternatives, geological environment, and geotechnical aspects.
