Geotechnical Problems of Tartu Old Town

This article analyses the formation of soil properties and the behaviour of buildings in Tartu Old Town. For assessing this, data was gathered from settled constructions, which showed that geotechnical actions change the properties of fluvial sediments variously and as such need thorough research. The preservation of wood used in foundations depends on their placement in geological layers, on the fluctuations of surface water and the geotechnical solutions used. The effects of geotechnical actions conducted before need more attention and therefore new projectsolutions in Tartu Old Town need thorough geotechnical research in each case.
