This project is a part of the TRUST (TRansparent Underground STructure) framework. The background of the TRUST project springs from a need to build more cost-efficient underground structures. While keeping costs at a minimum, the demands for sustainable, safe and easily maintainable underground structures are not to be neglected. Lifecycle costs for the structures must be considered. A significant driver for this is a recent development of stricter national and European regulations on energy and environment. The overall vision of the TRUST project is to:
- Promote research on development of sustainable urban underground infrastructure design
- Develop improved methods and tools for better planning, design, and construction of urban underground structures.
The TRUST framework consists of a set of subprojects focusing on holistic site investigation methods (TRUST 2.1, 2.2, 2.3 and 2.4), smart underground construction (TRUST 3.1, 3.2 and 3.3) and information models, data structure and visualization (TRUST 4.1 and 4.2).
Researchers that participated in TRUST 4.2 are Marcus Wennermark, Kristofer Hellman, Mathias Ronczka, Thomas Günther, Torleif Dahlin, Roger Wisén and Matteo Rossi.
A reference group consisting of the following participants supported the project researchers with valuable suggestions and comments on the planning, activities, and results: Mehrdad Bastani (SGU), Lena Persson (SGU), Andreas Pfaffhuber (NGI), Sara Bazin (NGI), Christel Carlsson (SGI), Malin Norin (NCC), Robert Sturk (Skanska), Johanna Gottlander (Trafikverket), Thomas Sträng (SLL) and Per Tengborg (BeFo).
A scientific advisory board have contributed with valuable comments and advice. They consisted of the following persons: Lee Slater (Rutgers University, USA), Willian Powrie (University of Southhampton, UK), Geoff Watson as stand-in 2016 (University of Southhampton, UK), Andrew Binley (Lancaster University, UK), and Panagiotis Tsourlos joined the group 2016 (University of Thessaloniki, Greece).
The project was funded by Rock Engineering Research Foundation (BeFo) and SBUF, the latter with Skanska as industry partner with Robert Sturk as project responsible. Byggrådet provided complementary funding that made it possible to involve Roger Wisén. Lund University and LIAG (Leibnitz Institute of Applied Geophysics) contributed with in-kind funding. Additional funding that made the extensive field tests possibly came from Nova FoU, Skanska and the Swedish Transport Administration.
The seismic refraction and ERT measurements in the Lake Mälaren survey at Hägersten were collected in close collaboration with Rambøll Denmark A/S using the methodology developed in this project. Rambøll Denmark A/S also processed the seismic data. The survey was funded by Stockholm Water, and the project appreciate the permission to use the data as part of the research project.
