  1. 1. Soil behavior at freezing and thawing

    Author : Sven Knutsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Avhandlingens första del behandlar en teoretisk beräkningsmodell för tjällyftning samt studier av dess noggranhet i olika situationer. Tjällossningsförloppet analyseras och studeras genom noggranna mätningar av porvattentryckens fördelning i tid och rum. READ MORE

  2. 2. Compaction and thaw deformation of frozen soil : permeability and structural effects due to freezing and thawing

    Author : Peter Viklander; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : This thesis is the result of the two projects:"Deformations in winter compacted soils" and "Permeability changes in a fine-grained till due to freeze/thaw". The aim of the first project was to study whether it is possible to compact frozen soils, in road embankments etc. READ MORE

  4. 4. Soil structure and water functions in agricultural soils of the temperate-boreal zone in a changing climate

    Author : Tobias Klöffel; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Climate change may affect the productivity of cropping systems in the temperateboreal zone by increasing the frequency of periods with water excess and shortage. Soils have the capacity to buffer such extreme weather events by regulating water storage and fluxes, which are mainly a function of soil structure. READ MORE

    Abstract : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. READ MORE
