1. 1. Mechanical Behavior of Tailings : Laboratory Tests from a Swedish Tailings Dam

   Författare :Riaz Bhanbhro; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailings dams; Tailings; Mechanical Behavior; Oedometer; Direct Shear; Triaxial; Shear strength; Soil Mechanics; Geoteknik;

   Sammanfattning : Tailings is leftover material from mining industry and is produced in huge quantities approximately 70-99% of the ore production.  Tailings material is stored as impoundments by constructing tailings dams which are often constructed with tailings material itself. LÄS MER

3. 2. On the impact of temperature perturbations on the creep of sensitive clay

   Författare :Yanling Li; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thermal cycles; sensitive clays; oedometer tests; temperature; natural bonding; apparent preconsolidation pressure; multi-physics modelling; geothermal; static thermal loading;

   Sammanfattning : Temperature affects the soil response, but is not fully understood and quantified and thus often ignored. The temperature fluctuations resulting from energy foundations and construction activities, such as excavations and soil stabilization, however, may lead to changes in the hydromechanical response of the clay.

4. 3. Calculating long-term settlement in soft clays - with special focus on the Gothenburg region

   Författare :Mats Olsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft clay; long-term settlement; creep; test sites;

   Sammanfattning : Long-term settlement in clay constitutes an engineering challenge in road design and construction in areas with deep deposits of soft clay. Soil improvement and construction of building foundations or embankments can be quite complicated and expensive in such areas. Construction costs need to be balanced against high maintenance costs.

5. 4. 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.

7. 5. Preconsolidation Pressure of Soft, High-plastic Clays

   Författare :Göran Sällfors; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In the early days only the ground that was best from a geotechnical point of view was used for foundations, but now, owing to the growth of cities and to the rising prices of land, softer and more compressible soils, less suitable for foundations, are also often used.The choice of foundation method is both economically and techni­cally an important matter, and thorough testing of the soil is often needed to determine its geotechnical properties, and thus, to furnish necessary information.
