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

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

    Abstract : 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. READ MORE

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

    Author : Yanling Li; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Geotechnical Aspects of Buildings on Expansive Soils in Kibaha, Tanzania : Preliminary Study

    Author : Charles Lucian; Staffan Hintze; Bo Berggren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; expansive soils; soil properties; potential swell; Soil-Structure Interaction SSI ; and superstructure and substructure.; Building engineering; Byggnadsteknik;

    Abstract : The focus of this study is on potential problems resulting from construction on expansive soils in Kibaha region, Tanzania. For the fact that most of the affected structures are founded on expansive soils, a clear understanding of the soil behaviour and their interaction with structures, specifically as they relate to shallow foundations, has been of more interest to the study in order to evaluate properly the source of the problem.

  6. 4. The Unloading Modulus of Soft Soil: A Field and Laboratory Study

    Author : Jenny Persson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swelling; heave; Clay; case study; excavation;

    Abstract : Improved infrastructure in urban areas often necessitates underground construction, where the unloading behaviour of the soil is of importance for predicting the amount of heave and how long it will take for the soil to swell. It is of particular interest to study the need for the installation of tension piles, as well as whether the tunnel will be subjected to settlement or heave in the long term. READ MORE

  7. 5. Testing and modelling of silty and sulphide-rich soils

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

    Abstract : 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. READ MORE
