Acciona and Smart Engineering collaborate on the structural optimization of the line segments of Follo Line Project in Norway

News

Since late last January, Smart Engineering collaborates with the Joint Venture AGJV, consortium of Acciona and Ghella. AGJV was chosen by the Norwegian National Rail Administration to build the double railway tunnel framed in the Follo Line project, the largest project Norwegian transport infrastructure. More details on this project are detailed in this link. The total cost of the project, considering the design and construction of the tunnels, stands at 1,000 million euros. These tunnels, designed for the circulation of high-speed trains, will be the longest in Scandinavia, with 20 km in length.

Smart Engineering will assess the ductility of the reinforcing strategy which will be used in reinforced concrete the segments that make up the segments of the tunnel. The main objetive of Smart Engineering in this project is to optimise the structural reinforcement of the line segments. To this end, a fibre reinforced concrete solution will be proposed considering structural fibres to substitute part of the traditional reinforcement. The security and structural reliability criteria stablished by the customer will be maintained with this solution. Fibre reinforced concrete solutions are highly efficient in these applications and can reduce overall costs of the project.

The reinforcement optimisation will be tackled both by numerical analysis and throughout a comprenhensive experimental campaign in laboratory. Smart Engineering will provide their expertise in optimizing concrete reinforcements using fibre reinforced concrete. This is possible by using sectioanl calculus tools to determine the equivalente reinforcement strategy by using fibre reinforced concrete.

During the past 2015 Smart Engineering collaborated with the company FCC, which is participating with other international companies in the Joint Venture Fast Consortium, responsible for the construction of underground tunnels of Ryiadh. This work, one of the most ambitious internationally in underground construction, is facing major challenges and requires advanced structural engineering processes. One of the most important challenges is given by the extreme weather conditions in Saudi Arabia. These conditions make it difficult to ellaborate the line segments of the tunnel made with reinforce concrete.

Smart Engineering conducted an advanced structural engineering study to determine the effect of the extreme conditions that occur in that part of the world, in the development and curing stages of the reinforced concrete segment linings. Especial attention was given to the effect of high temperatures and low humidity. Such conditions may influence the curing process and develop internal stresses in the material. This study allowed Smart Engineering to propose innovative engineering solutions related to the ellaboration of structural concrete in extreme climate conditions.
