1. 21. Mechanical properties of stabilized dredged sediments : for sustainable geotechnical structures

   Författare :Gregory Paul Makusa; Göran Holm; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

   Sammanfattning : Dredging activities at Ports and Harbors are inevitable for the safe navigation of ships and vessels. Dredged material may range from very fine and contaminated sediments to sand and gravels. While, granular dredged material can be directly utilized in civil engineering applications, fine sediments may require further treatment before use. LÄS MER

3. 22. A Critical Review of the Observational Method

   Författare :Johan Spross; Stefan Larsson; Fredrik Johansson; Joakim Jeppsson; Lars Rosén; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock mechanics; observational method; Eurocode 7; reliability analysis; dam safety; tunnelling; system reliability; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Building a sustainable structure in soil or rock that satisfies all predefined technical requirements implies choosing a rational and effective construction method. An important aspect is how the performance of the structure is verified. LÄS MER

4. 23. Performance of landfills of hazardous waste with special respect to the function of clay liners

   Författare :Laith Al-Taie; Rolf Sjöblom; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

   Sammanfattning : This licentiate thesis is based on four papers related to the performance of near-surface low-level (LLW) repositories (landfills) focusing on construction and performance of clay liners in the cappings. The first paper discusses the source of hazardous wastes, their location and their impact on public health. LÄS MER

5. 24. The behaviour of mica-rich aggregates under the temperate climate conditions

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

   Sammanfattning : In regions of temperate climate the destructive influence of frost action such as frost heave in winter and thaw weakening in spring are the main contributors to severe deterioration of the pavement structure. A number of studies on construction aggregates and field observations of road failures, especially caused by seasonal fluctuations of temperature, have revealed a negative influence of unbound mica-rich rock aggregates on the service life of road construction.

7. 25. Kompressionsegenskaper hos sulfidjordar : En fält- och laboratoriestudie av provbankar

   Författare :Mattias Andersson; Lars Eriksson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

   Sammanfattning : In this licentiate thesis is presented the work and the results of the construction of two testembankments on sulphide soils at the test field in Lampen outside the city of Kalix next to thenew rail road Haparandabanan.The main purpose of the licentiate thesis work was to improve the knowledge of compressionproperties of sulphide soils, with focus on the creep properties.
