3. 12. Pore pressure response in the uppermost part of a clay soil slope - Two case studies in the Gothenburg region

   Författare :Hanna Blomén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; yearly variations; simulation; precipitation; pore pressure; clay; slope stability;

   Sammanfattning : In this research project the pore pressures in the uppermost 5 to 10 meters of clayey soils in southwestern Sweden are studied. The focus is on natural, short time variations, such as yearly variations due to precipitation, frost and evaporation. LÄS MER

4. 13. Embankments founded on sulphide clay : - some aspects related to ground improvement by vertical drains

   Författare :Rasmus Müller; Stefan Larsson; Göran Sällfors; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geotechnical engineering; embankments; vertical drains; sulphide clay; Earth sciences; Geovetenskap;

   Sammanfattning : In this thesis, some aspects concerning building embankments founded on sulphide clay are studied, with special reference to ground improvement by preloading in combination with prefabricated vertical drains (PVD’s). The main purpose of the research was to increase empirical knowledge of the mechanical behaviour of sulphide clays subjected to embankment loadings and of the interaction between vertical drains and sulphide clays.

5. 14. 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.

7. 15. Slopes in soft clay - management of strength mobilisation

   Författare :Victoria Svahn; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remedial measure; dry crust; climate change; Slope stability; pore water pressure; in situ stress; soft clay; shear strength mobilisation;

   Sammanfattning : Many natural and man-made slopes close to buildings or infrastructure do not demonstrate sufficient levels of safety with respect to their stability. Nonetheless, it is a requirement from society that the environment we live in is safe. LÄS MER
