Sustainable infrastructure and foundations supported by advanced characterization of soil

The purpose of this project is to investigate and describe the geotechnical parameters that characterize the stiffness of glacial moraine deposits, which are common in Denmark and the rest of Scandinavia. Moraine deposits are characterized by being unsorted and consisting of all grain sizes. Therefore, a greater scattering on derived parameters is often observed, compared to other soil types. The consequence is a greater uncertainty associated with design values of geotechnical properties and oversizing as a result. In addition, the project will build experimental equipment, which will be used to assess stiffness parameters on the basis of stress and strain levels and especially for very small strains. Contemporary foundations and excavations in the vicinity of existing structures must be secured against even small movements. This means that the stiffness associated with small strains determines the dimensioning of frame walls and foundations.
