    Sammanfattning : Artificial ground freezing as a method to temporarily stabilize and create hydraulic sealing in urban as well as in rural areas has been used in a number of Swedish construction projects, particularly during the last decade. One problem with the freezing of soil and rock is that fine-grained clayey types of soils have showed a tendency to under certain circumstances, during the thawing process, create a pore water overpressure and to consolidate, despite a change in the external loading conditions.

    Sammanfattning : The aim of the thesis is twofold: to analyze the effects of the expectations on the Bothnia Line on the housing market and expectations on railway use. To fulfill these aims, three questions are considered:1. To what extent is property prices influenced by the expected effects of the Bothnia Line?2. LÄS MER
