LimitState:GEO uses DLO, a powerful general purpose analysis method. Model any type of geotechnical problem without worrying about how appropriate or accurate the solution will be.
Dispose of slip circles, slices, Terzaghi equations and their associated limitations. Model the real-life circumstances and develop better solutions based on an accurate understanding of the critical failure state.
Slope stability analysis with LimitState:GEO is as straightforward as using the conventional 'method of slices', but with entirely flexible slope geometry and load definition.
The underlying Discontinuity Layout Optimization (DLO) technology allows the software to automatically search all possible failure modes - even when they are highly non-circular. There’s no need to specify entry/exit points, solution method, inter-slice force functions or search spaces.
Include features such as retaining walls, piles, reinforcement and much more while identifying the critical slip surface and associated factor of safety within seconds.

Slope stability analysis with LimitState:GEO is straightforward, but allows great flexibility.
With Limitstate:GEO you can rapidly assess for multiple failure types, including internal wall failure.
With LimitState:GEO you can analyse and design cantilever stem walls with speed and accuracy. The software allows fully flexible definition of wall geometry, fill geometry and loading conditions, making it easy to assess scenarios involving complex layered soils and surcharges.
The state-of-the art solver will rapidly find the critical mode of failure without the need to consider separate types. Simultaneously check for external failure (e.g . sliding, bearing, overturning or global failure) or internal failure (e.g. shear and moment failure) and be confident that the critical case has been identified.

LimitState:GEO models reinforcement and soil interaction in a fully general way, using the same familiar principles used in conventional methods such as the ‘tie-back wedge’ approach, but effectively allowing thousands of wedges to be modelled simultaneously.
Whether the model includes 1D elements, such as nails and anchors, or 2D features like geotextiles, LimitState:GEO will quickly and automatically determine the critical mode of failure and associated factor of safety without the need to separately consider internal or external failure, pullout length, rupture etc.

Soil reinforcement in LimitState:GEO (such as reinforced walls) uses familiar principles, but allows thousands of possibilities to be modelled simultaneously.
LimitState:GEO provides the flexibility to model any foundation geometry, as well as more complex features, such layered soils and nearby trench excavations.
LimitState:GEO is the ideal tool for foundation analysis and design. Built-in wizards allow rapid definition and analysis of standard foundation types, while the software provides the flexibility to model any foundation geometry, fill geometry and load definition, allowing more complex structures to be investigated. Problem features such as surcharge loading, layered soils and nearby trench excavations can all be considered with ease.
The state-of-the-art Discontinuity Layout Optimization (DLO) solver engine automatically finds the critical mode of failure, allowing rapid analysis of without the need to specify the failure mode in advance. Slip-line singularities and fan-zones, often a problem in Finite Element Analysis based software, are identified and treated without difficulty.

The LimitState:GEO seismic analysis functionality allows a pseudo-static analysis to be undertaken on any problem geometry. The dual-mode approach allows the effect of an additional fixed horizontal and/or vertical acceleration to be investigated, or the value of the acceleration required to trigger instability to be determined.
The flexible modelling capabilities of LimitState:GEO allows complex problems, such as quay wall collapse, to be straightforwardly modelled. Determining the horizontal acceleration required, e.g. to reach a specific active earth pressure on a retaining wall, is a quick and simple process.
Determine the value of acceleration required to trigger instability using the Limitstate:GEO seismic analysis functionality.
Quickly define and solve complex gabion wall problems using LimitState:GEO.
With LimitState:GEO, setting up and solving a gabion wall analysis is simple. Define geometries using the built-in wizard, or by importing a ready-made DXF file. Model surcharge loads, layered soils and complex geometries directly, without using correction factors.
LimitState:GEO automatically searches all possible failure modes every time you solve. This means that you can be confident that the critical case has been identified. Check millions of potential failure modes - including sliding, overturning, bearing, internal wall failure as well as global collapse.

LimitState:GEO is the ideal tool for analysing the stability of gravity retaining walls. While traditional methods require a predetermined failure type to be specified, the use of Discontinuity Layout Optimization (DLO) means that, with LimitState:GEO, the critical mechanism and associated factor of safety are automatically identified with the click of a button.
The state-of-the-art solver engine will rapidly consider all possible failure modes, including sliding, bearing, overturning and global failure, as well as potential internal failures due e.g. to shear. With the ability to easily incorporate unusual geometries and loading, it is easy to check for other scenarios such as an excavation or surcharge loads.
Gravity walls are checked for all possible failure modes without the need to specify the type or shape in advance.
Complex features, such as sheet pile walls, props and anchors can all be easily incorporated into a LimitState:GEO model.
With LimitState:GEO, the modelling of deep excavations is made simple. Complex geometries, loading and ground conditions can all be incorporated, as well as more complex features such as sheet-pile walls, props, anchors and inclined water tables. The rapid setup and solve workflow allows solutions for staged works and ‘what if’ type problems to be determined quickly and accurately.
The Discontinuity Layout Optimization (DLO) analysis method will rapidly analyse all possible modes of failure and report the critical case, whether that involves base heave, wall collapse, structural failure or a combination of these.
