2. 1. Progressive landslides in long natural slopes : Formation, potential extension and configuration of finished slides in strain-softening soils

   Author : Stig Bernander; Steinar Nordal; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik; Soil Mechanics; Geoteknik;

   Abstract : After the large landslide in Tuve (Gothenburg, 1977), the author began developing a finite difference model for slope stability analysis taking the deformation-softening of soft sensitive clays into consideration. In the model, the mean down-slope deformation in each element caused by normal forces is maintained compatible with the deformation generated by shear stresses. READ MORE

   Abstract : For an efficient mining operation, it is essential to have as much information as possible aboutthe ore to be excavated and the rock masses surrounding the ore. Geological information andthe content and distribution of extractable minerals, are central concerns for long term mineplanning. READ MORE

5. 3. On modelling of slope stability in sensitive clay

   Author : Carolina Sellin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constitutive modelling; mobilisation of shear strength; destructuration; slope stability; anisotropy; sensitive clay; rate dependence;

   Abstract : The stability of natural slopes is a global problem, with the number of landslides and the associated socioeconomic losses increasing, as a result of the global trend of urbanisation, deforestation and changed weather patterns. The available methods for identifying potential failure modes and assessing the stability, however, overly simplify the modelled soil behaviour within a slope, which might lead to unnecessary mitigation measures or non-conservative results.

6. 4. On the behaviour of tailings dams : Management in cold regions

   Author : Roger Knutsson; Jan Laue; Andy Fourie; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

   Abstract : Associated to mining activities there is mine waste generated. The residues left over from mineralextraction processes are referred to as tailings, normally stored in surface tailings facilities. Thefacilities are usually confined by embankment dams, so called tailings dams. READ MORE

7. 5. Mechanical properties of stabilized dredged sediments : for sustainable geotechnical structures

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

   Abstract : 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. READ MORE
