Abstract [en]

The climate change is expected to have serious implications for large sectors of the infrastructure and the built environment. Spatial planning needs to take greater account of changes in the ground and to the sustainability of the ground for construction. To address these challenges the Swedish Geotechnical Institute (SGI) took the initiative to an Action Plan for sustainable ground construction (SGI, 2017) to provide a basis for concrete measures, future discussions and inter-agency collaboration within the geoconstruction sector. The Action Plan is based on discussions with about 200 stakeholders from more than 70 different organisations and it highlights what needs to be achieved, how it can be achieved and suggestions who can take the initiative. However, the work with the Action Plan also revealed the need for a more specified description on how different geoconstructions geotechnically are affected by climate loads based on future climate scenarios. This paper present the result of a synthesis report including the climate changes for Sweden, which implies changes in temperature, precipitation and wind. These climate parameters mean that natural ground and geoconstructions are increasingly exposed to changing load levels due to changes in the groundwater level, changes in water flows and changing drought, snow cover and frost conditions. The paper present todays knowledge about future climate loads and how natural ground, substructures and superstructures, dewatering plants, ground reinforcement, support structures and foundations are affected. It also presents lack of knowledge and propose some suggestions for research and development.
