1. 1. On modelling of slope stability in sensitive clay

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

   Sammanfattning : 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.

3. 2. On Probability in Geotechnics. Random Calculation Models Exemplified on Slope Stability Analysis and Ground-Superstructure Interaction

   Författare :Claes Alén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; random; creep; slope stability; calculation; interaction; design; limit state; probability; statistics; geotechnics;

   Sammanfattning : The thesis deals with uncertainty in calculation modelling. Emphasis is put on the design state. Design is a chain of decisions under uncertainty. A probabilistic approach is used to describe the uncertainty and calculations as a way to reveal the uncertainty. LÄS MER

4. 3. Numerical analyses of stability of a gradually raised tailings dam

   Författare :Muhammad Auchar Zardari; Daichao Sheng; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tailings dams; consolidation; rockfill berms; slope stability; corner; internal erosion; finite element analysis; Soil Mechanics; Geoteknik;

   Sammanfattning : Numerical analyses are presented in this thesis to address potential stability problems that may occur during gradual raisings and under seismic loading conditions of Aitik tailings dam in northern Sweden. The dam is mainly raised using upstream construction method. It is planned to raise the dam gradually in several stages. LÄS MER

5. 4. Electrochemical water splitting based on metal oxide composite nanostructures

   Författare :Aneela Tahira; Omer Nur; Magnus Willander; Rasit Turan; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Composite metal oxides; hydrothermal method; water splitting; Tafel slope; stability; durability; alkaline media; acidic media;

   Sammanfattning : The occurrence of available energy reservoirs is decreasing steeply, therefore we are looking for an alternative and sustainable renewable energy resources. Among them, hydrogen is considered as green fuel with a high density of energy. LÄS MER

7. 5. Estimation of pore pressure levels in slope stability calculations: Analyses and modelling of groundwater level fluctuations in confined aquifers along the Swedish west coast

   Författare :Håkan Persson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HBV; pore pressure; groundwater level; slope stability; landslide; model; climate change; confined aquifer;
