Slope Failure Analysis

• Definition of any kind of abrupt typographical change
• Hills, valleys as well as free groundwater tables in the form of lakes can be modelled
• Definition of the soil layer model on the vertical section via sampling points
• Alternative definition of the soil layer model by free polygonal modelling of the soil layer boundaries

Soil

• Any number of soil layers with polygonal boundaries
• Freely selectable soil parameters
• Definition of self-contained soil layers (e.g. lenses or impermeable cores)
• Classification of soil types as per DIN 18196 with admixtures

Ground surface

• Any kind of polygonal ground topography
• It is possible to model several hills and valleys

Groundwater

• Freely selectable presence of groundwater in the form of a polygonal seepage line
• Free water tables in the form of lakes
• In the slope failure calculation, groundwater can be considered either via the pore water pressure as an internal force or hydrostatically via the water pressure as an external force

• Application of line, area and moment loads
• Line loads can also act horizontally
• Application of loads as surface loads or, optionally, as acting at a freely selectable depth z
• Free assignment of loads to a type of action as per EC 0.
• Verification method 3, where partial safety factors are applied to actions and the geotechnical parameters, is used.

• Selection of the design situation (persistent BS-P or transient BS-T)
• Definition of a centre grid for the slip circle variation
• Definition of the number of slices
• Limitation of the slip circle variation by defining the required minimum depth to which the slip circle must penetrate the ground, the maximum number of variations and the number of radii to be investigated

• Representation of the utilization in the variation grid in the form of numerical values or a colour scheme
• Calculation with automatic slip circle variation by specifying a fixed slip circle geometry

• They describe the lower endpoints of rigid structures such as foundations, anchors, piles etc.
• They are used to limit the slip circle variation
• They must lie inside the decisive slip circles
• Rigid bodies cannot be intersected by the slip circle above their endpoints (rigid body points)

• To limit the slip circle variation
• One or two constraint points are possible
• Positioning of constraint points, e.g. at the slope bottom

• PDF
• Word
• Printer

• Various output profiles are available for selection (brief, detailed, user-defined)
• Detailed output of the force relationships at the slices
• Result graphics can be put out optionally

• Detailed tabular compilation of all slice forces
• Comparison of the driving and retaining moments around the decisive slip circle centres with associated utilization

• DIN EN 1997 
• ÖNORM EN 1997 
• DIN 1054 in conjunction with DIN 4084
