Abstract [en]

When building a house or similar the stress on the ground increases and deformations can arise. The deformations create a foundation that the building is not constructed for and damages on the building arise. The increased stress on the ground can be derived back to the building, but it is possible that the increased stress may well derive from different sources such as other buildings or trees.      

 

The building is an older property, built in the late 19th century alternatively early 20th century, and is today used for rental housing and has suffered severe damages due to subsidence. The goal of the thesis is to find possible causes for these subsidences.

 

The thesis was executed as a combination between literature- and casestudie.

 

After careful studies it has been found that a probable cause for these subsidences is trees. Through field- and lab studies it has been found that the trees has effected the ground through there accumulation of water. This has caused the soil to dry up and subsidence’s has probably arisen through the decrease in pore pressure due to the disappearing of water. This, however, needs to be proven by further studies of pore pressures in the area.
