TUNCONSTRUCT

from Wikipedia, the free encyclopedia

TUNCONSTRUCT was a European research project to research and develop innovative methods, materials and machines to improve the design, construction and maintenance of tunnels . TUNCONSTRUCT consisted of 41 partners from eleven European countries and was co-financed by the European Commission in the 6th Framework Research Program with 26 million euros , which corresponded to 54% of the total budget. The project started on September 1, 2005 and was completed by the end of August 2009. It involved both universities , as well as companies and engineering firms. TUNCONSTRUCT was divided into four sub-projects, which are described in more detail below.

design

The design of tunnels should be simplified by developing a design support system. This system should encompass the entire design process, from recording the geology to assessing individual design variants. By combining digitized data acquisition, numerical simulations and knowledge-based methods , a software platform had to be created that would enable “computer aided tunnel design”.

Technologies

By developing new technologies and improving existing methods, the construction of underground structures should be made more economical and less risky. As part of the sub-project, for example, new materials or cement mixtures for lining segments or shotcrete were developed and tested, and tunnel boring machines were further developed with the aim of increasing their excavation cross-section.
