The model collapses, meaning that the peak acceleration is too much for the model (of course after checking. The condition of the analysis is the initial condition of the slope and condition after being given a reinforcement, where the reinforcement that is used in this analysis is sheet pile.When conducting pseudo static slope stability in plaxis for a certain kh value of 0.4. In this thesis, slope stability is analyzed by 2 methods, named by Plaxis 2d V8 and the analytical method called Bishop method.

Starting File “GTS 2D Tutorial38_start.gtb” 5. Factor of safety (FOS) assessed for the assumed virtual active surface and the critical cross section which has minimum FOS. Analysis performed assuming failure surface as Circular and Polygonal. SAM is used for analyzing the slope including weak layer. For 2D analysis of deformation and stability in geotechnical engineering and.2D Slope Stability Analysis using SAM Overview1.

Double click ‘GTS 2D Tutorial 38_start.gtb’ 3. Compare the FOS for the assumed active surfaces to those of current ‘SRM’, and verify the location of critical cross section which has minimum FOS.2. (Such areas are nonlinear material characteristics, stress history effect due to forming process, etc.) This method is a reliable evaluation method for the slope stability through the accurate FEM a nalysis results7. This method allows users to perform the analysis of the areas which were unable to solve with current ‘li mit stability method’. SAM(Stress Analysis Method) here applies ‘virtual active surface’ which is an evaluation element in ‘limit stability method’ into the FEM analysis results. Assuming the virtual active surfaces as circular or non-circular, and calculate the FOS for every active surface assumed.Midas GTS provides FEM ‘slope stability analysis’ (SAM) using ‘Strength Reduction Method’ (SRM) and ‘limit stability method evaluation elements’ as a stability evaluation method for slopes.

Select the edges of the ‘WeakSoil’ as shown 2. Type > ‘Quadrilateral’Procedure 1. Attribute > ‘1’ : Weathered Soil’, Mesh Set Name> ‘Weathered5. Mesh Size > Enter ‘1’ in the Element Size 4. Select the edges above the ‘Weak Soil’ as shown 3. Main Menu > Mesh > Auto Mesh > Planar Area… 2.

‘Weathered Soil’ and ‘WeatheredSoil 2’ are two different Mesh Sets however, they can be easily merged because they share the same properties 3. Verify that Default Mesh set is included 2. After generating the Mesh, verify that 3 Mesh Sets have been defined. Similarly create a mesh set for the Weathered Soil below the Weak 4Procedure 1.

Enter the Grid Range Reference Points 1 and 2 for (X, Y) coordinates (28,24), (38,24) respectively. BC Set > enter ‘Circular’ 33.

After adjusting Circular Slip Surface settings, the color labels of the Grid Ranges or RadiusRanges from the Mesh Set can be assigned a different color by calling the following command: View > Display Option > LBC > Grid and Radius for Slip SurfaceModel > Boundary > Slip Surface >CircularProcedure 1. The Grid & Radius Range can be adjusted by right clicking the mouse button and selecting the ‘Edit’ command 33.
