1. 1. Embankments founded on sulphide clay : - some aspects related to ground improvement by vertical drains

   Författare :Rasmus Müller; Stefan Larsson; Göran Sällfors; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geotechnical engineering; embankments; vertical drains; sulphide clay; Earth sciences; Geovetenskap;

   Sammanfattning : In this thesis, some aspects concerning building embankments founded on sulphide clay are studied, with special reference to ground improvement by preloading in combination with prefabricated vertical drains (PVD’s). The main purpose of the research was to increase empirical knowledge of the mechanical behaviour of sulphide clays subjected to embankment loadings and of the interaction between vertical drains and sulphide clays.

3. 2. Testing and modelling of silty and sulphide-rich soils

   Författare :Yao Yu; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

   Sammanfattning : Silt and sulphide soil are two types of soil which are dominating in northern Sweden, especially in the coast area of the Baltic sea. The stress-strain and strength characteristics of these two soils have so far not been as much explored as those for e.g. Scandinavian clays. LÄS MER

4. 3. Remediation of mercury polluted soil

   Författare :Thomas Lifvergren; Bert Allard; Örebro universitet; []
   Nyckelord :soil pollution; soil remediaion; mercury; NATURAL SCIENCES; NATURVETENSKAP; Enviromental Science; Miljövetenskap;

   Sammanfattning : Mercury in contaminated soil constitutes a wide spectrum of species with highly different properties due to the chemical complexity of the element. Assessments of risk, ecological effects and removal potential require process and mobility studies. LÄS MER
