2. 1. Development of a Methodology for Dynamic Testing of Rock Support : Field Tests and Numerical Analysis

   Author : Shahin Shirzadegan; Erling Nordlund; Ping Zhang; Charlie Chunlin Li; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : The increasing mining depth in the Luossavaara-Kiirunavaara Aktiebolag (LKAB) mine located in the northern part of Sweden leads to higher stress magnitudes, resulting in increased seismic activity and more seismically-induced damage. The effectiveness of various ground support systems under dynamic loading conditions has therefore become of prime interest to LKAB for successful and safe mining at deep levels. READ MORE

4. 2. Modelling of Groundwater Conditions in Silts and Fine Sands. A Study of Induced Groundwater Changes Based on Laboratory and Full-Scale Field Tests

   Author : Marius Tremblay; Chalmers University of Technology; []
   Keywords : fine sand; laboratory tests; numerical simulation; silt; soil mechanics; groundwater; pore pressure; field tests; soil matric suction; partially saturated soil; groundwater conditions;

   Abstract : Every day, geotechnical engineers have to deal with groundwater problems. In order to find suitable solutions to these problems, modelling of the groundwater conditions and their variations in time has to be performed. A study of the groundwater conditions in silts and fine sands was made including laboratory and full-scale field tests. READ MORE

5. 3. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations

   Author : Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

   Abstract : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. READ MORE

6. 4. Hydraulic Conductivity of Saturated Sand-Bentonite mixtures

   Author : Malin Sundsten; Chalmers University of Technology; []
   Keywords : quarry sand; design; bentonite; landfill barrier; field tests; dry density; foundry green sand; laboratory tests; hydraulic conductivity;

   Abstract : The implementation of the EC directive concerning landfill liners and covers sets stricter technical and environmental requirements for landfill barriers. It is therefore essential to identify suitable materials that fulfil these requirements. READ MORE
