Benefit from multiplane analysis MPA , which offers enhanced spatial slope stability analysis. Save time with automatic sliding direction determination, efficient search methods, probability analysis, and sensitivity analysis. Design to standards like Eurocode 7 or BS Incorporate reinforcements, dynamic loads, unsaturated conditions, climatic effects, and anisotropic bedding.
Once the conceptual model was built, Tierra Group was able to analyze multiple potential failure locations and orientations in excellent time. We highly recommend this software for analyzing similar projects. We hope that we can continue working together.
Anddes needed reliable 3D slope stability program to handle both strong and weak layers in the waste dump toe foundation, actual dike geometry, and actual 3D geometry. Take advantage of finite element method and limit equilibrium method capabilities for the design and analysis of soil, rock, and associated structures.
Trust the 3D geotechnical analysis that has proven robust and reliable in settlement, stress, and safety analysis for more than 25 years.
Summary Students survey a local landslide that has formed in fill using a total station. This activity is used in my geomorphology course for geology majors. Have completed some factor of safety calculations Able to create topographic profiles from topo maps Familiar with Coulomb's equation, cohesion, internal friction, pore water pressure.
We do this activity after discussing the role of cohesion, internal friction and pore water pressure, and have solved some relatively simple factor of safety problems using excel. Recognize assumptions and limitations of modeling slopes Gain experience with varying values of the cohesion, internal friction and pore pressure and how it affect the factor of safety Compare results of their model with the reality in the field - does the model represent the reality well?
Use historical topographic maps Use topo maps and survey data to create multiple topographic profiles Use a total station Make a topographic map of the slope and landslide additional activity.
Students in geomorphology go on a field trip to view some local landslides, including a large one that has formed in fill from a highway project.
Students walk then entire extent of the landslide and describe the features they see. We discuss what kind of landslide do they think it is and why do they think it formed here? If we have more time available, we will place flags within the slide and slope, and we do a more complete survey. Students will then use a base map from this topographic data and return and map the landslide features and create their own topo map of the slope. Features of this simulation include: Spencer analysis method, homogenous material using the Mohr Coulomb soil model, a dry slope with no pore-water pressure, two sloping anchors, and the entry and exit slip surface option.
Mechanically stabilized earth MSE walls are structures for retaining the earth under bridges, highways, and waterfront properties, to name a few. Designing a MSE wall requires consideration of the geometric configuration and reinforcement requirement to ensure both internal and external stability.
Choose options for limit equilibrium or finite element stress methods, pore-water pressures, trial slip surfaces, tension cracks, probabilistic and sensitivity methods, pseudo-static loading, partial factors, convergence criteria, and more. Define the material properties for your analysis, assign them to regions on the domain, and then define your initial pore-water conditions.
Select from a comprehensive list of soil and rock material models including Mohr-Coulomb, undrained, high strength, impenetrable, bilinear, strength as a function of depth, anisotropic strength, generalized shear-normal function, SHANSEP, and generalized shear-normal function for typical rock material models including Hoek-Brown.
Define the pore-water pressure conditions as either piezometric lines, spatial functions, finite element computed, or Ru and B-bar approaches. Define slope reinforcement properties to simulate ground anchors, soil nails, piles, or geosynthetics. Define surcharge loads to simulate a pressure applied over a portion of the ground surface, such as a footing.
Any other loads can be modeled on the domain as a point load. You can also specify seismic loading on the domain by setting horizontal and vertical coefficients that represent a force created by seismic or earthquake accelerations.
A number of options for specifying slip surfaces are available, including as entry and exit zones along the ground surface, a grid of slip surface centers and radius tangents, blocks of slip surface intersection points, or pre-defined slip surface line segments.
