Funkce

Analyze factor of safety
- Leverage our advanced strength reduction method analysis and accurately predict the degree of safety associated with the slope along with associated failure patterns. The strength reduction method is typically used for evaluating the safety of an embankment on soft soil with a high groundwater level and the impact of different construction rate. Safety factor evaluation analysis in PLAXIS can also be advantageously used in situations with strong structural interaction for which the evaluation of a failure mechanism on beforehand (as done in classical limit equilibrium analysis) cannot be achieved.
Apply absorbent model boundary conditions
- Apply advanced model boundary conditions when dynamic analysis requires special boundary conditions. In addition to viscous boundaries, free-field and compliant base boundaries can also be selected to reduce spurious reflections of waves from reaching the model boundaries.
Automate repetitive tasks with native command line
- Benefit from the additional access to specialized text commands that fully supports the PLAXIS modeling workflow and save valuable time in automating repetitive modeling tasks. Although all actions can also be accomplished through mouse clicks, the use of commands enhances the power of PLAXIS through automation workflows. Simply execute modeling operations and alternatively create PLAXIS model by alternatively entering text commands in the dedicated command line. Evaluate automatically generated text commands during interactive model-creating for further re-use or edition. Replay user-defined sets of text command for automated model creation.
Conduct dynamic analysis with earthquake data
- In modeling the dynamic response of a soil or rock structure, the inertia of the subsoil and the time dependency of the load are considered. The time-dependent behavior of the load can be assigned through harmonic, linear, or table multipliers. Via table input, users can import real earthquakes signals to perform meaningful seismic design of jetties or foundations. Dynamic multipliers can be assigned independently in the x- and y-directions in PLAXIS 2D dynamics feature and x-, y-, and z-directions in PLAXIS 3D dynamics feature.
Define realistic and accurate initial conditions
- Generate realistic initial stress and pore pressures fields in equilibrium with the soil weight through either K0-procedure or gravity loading. Automatically define state of over-consolidation for advanced constitutive models and set-up initial stresses in the soil body, considering both the influence of the weight of the material and the history of its formation. The field stress initial calculation complements the gravity-based initial stress definition and makes it easier to define the in-situ stress for the non-uniform deep ground conditions, such as those encountered in deep tunneling or reservoir geomechanics.
Determine stress change due to thermal loading
- Analyze displacements or the rotation of stress due to temperature changes. Coupling between thermal loading and mechanical process is required when the temperature change in soils results in thermal stresses. An example is the deformation of a navigable lock due to sunlight absorption when the lock is empty.
Evaluate flow-deformation coupling through consolidation analysis
- Precisely evaluate the mechanical process by which soil gradually changes volume in response to a change in pressure over time. Evaluate long-term settlement of foundations or earthworks over weak and non-permeable soil layer, such as marine clay. Safely evaluate possible technical risks associated with consolidation in areas like land reclamation, construction of embankments, tunnels, and basement excavation in clay.
Obtain accurate steady-state flow analysis for dewatering and groundwater control
- Easily generate non-hydrostatic pore water pressure distribution in the initial hydraulic gradients or after dewatering. Leverage water-level definition for fast and straightforward generation of boundary conditions for groundwater flow analysis. Evaluate steady-state temperature distribution for underground cable system of retaining wall under severe climatic conditions.
Optimalizace návrhu mrznutí terénu
- Ať už je mrznutí terénu umělé a za účelem zpevnění nestabilního terénu, nebo přirozené, můžete studovat komplexní souvislosti mezi rychlostí toku podzemní vody, teplotou mrznoucího potrubí a jejich dopady na tvorbu ledové stěny napříč různými hraničními podmínkami.
Perform time-dependent flow analysis
- Go beyond the default options of steady-state groundwater flow analysis PLAXIS Advanced with the PLAXIS Ultimate. Assign time dependent variation or fluxes to water levels, model boundaries, or soil boundaries to simulate various complex hydrological and/or thermal conditions. The input of the time dependent properties is based on harmonic, linear, or table functions. This allows seasonal variations of river water levels behind embankments and their effect on the overall slope stability to be modeled. Precipitation, wells, and drains can be included in the model, allowing pumping tests or other hydrological applications to be modeled.
