4. 18. Progressive landslides in long natural slopes : potential extension and configuration of finished slides in strain-softening soils

   Författare :Stig Bernander; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik; Soil Mechanics; Geoteknik;

   Sammanfattning : A finite difference method is presented for progressive slides in long natural slopes. The method is based on a strain softening material model. A detailed worked out example is given as well as examples using a spread sheet PC program and a PC program for Windows. LÄS MER

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

   Författare :Stig Bernander; Steinar Nordal; Luleå tekniska universitet; []

   Sammanfattning : 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. LÄS MER
