XDisp Pro is the ultimate tool for busy engineers working on major projects with multiple stages and challenges. Innovated with the assistance of Arup engineers and used on some of the largest infrastructure projects in the UK, it is proven to save thousands of hours of unnecessary development time.

With the release of XDisp 20.0 analysis and calculation time has been greatly reduced thanks to the enabling of multicore processing, maximising the usage of your hardware.

• Analyse inclined or horizontal soil interfaces.
• Calculate surface and sub-surface results.
• Examine excavations with inclined bases.
• Analyse models with multiple mines, excavations, tunnels, buildings and utilities.

Staged Construction is an innovative new feature that gives you unlimited analysis of different stages of the construction in a single model view. You no longer have to switch between model files and you can animate the visualisation of the analysis results to view how different structures, utilities, and railways react at different stages of the project.

Customise the visualisation by adding or removing features for clear presentation.

XDisp now uses the COM (Component Object Model) interface in a number of innovative ways. COM interface creates data objects that allow external programs to pass information and instructions to and from the other software programs. COM has already been used in research and it speeds up the analysis in geotechnical projects.

XDisp is the only software program available that offers such a range of assessment features.

• Assess building damage of Specific Buildings resulting from soil movements and produce building damage interaction charts.
• Assess building damage of Generic Buildings.
• Assess utility damage of Specific Utilities resulting from soil movements and produce utility damage assessment graphs.
• Assess utility damage of Generic Utilities.
• Assess rail damage

• Import background data from DXF files to provide a backdrop on which to enter model geometry graphically.
• Import geometries of excavations, tunnels and buildings from DXF files.
• Import displacements from other programs and combine them with those from XDisp.

• Input single or dual-layered soils.
• Dynamic chart views allows you to quickly switch between different analysis and assessment results.
• Bulk chart export any amount of analysis results.
• Enter field data to give improved sub-surface ground movements.
• Input, edit and delete elements via 3D graphics.
• Display results in 3D graphics.
• View results in plan, as contours or vectors.
• Produce line graphs of settlements and horizontal displacements.

Building Damage Assessments

Specific Building Damage Assessment is calculated using the Burland (1997) assessment method. Buildings are specified by their locations and bending properties. XDisp uses the analysis data to class the buildings into damage categories based on their tensile strains.

Generic Building Damage Assessment avoids detailed assessment of large numbers of buildings which are later found to experience damage within acceptable limits. The same assumptions and calculation methods which would be used for individual specific buildings are applied to representative sections transverse to a defined route. Along each section a number of different building geometries are analysed and the worst cases are assessed against standard criteria.

Utility Damage Assessment 

Specific Utility Damage Assessment is calculated by assessing the extent of rotation of joints, pullout of joints and axial and flexural strains. Utilities are specified by their locations, dimensions and acceptance criteria for rotation, pullout and strain. XDisp uses the analysis data at joints and reports whether the rotations, pullouts and strains calculated at joints satisfy their respective limiting criteria.

Generic Utility Damage Assessment is similar to damage assessment of Generic Buildings. Generic Utilities are assessed by applying the specific utility damage approach to representative sections along a route using different utility properties and diameters.

Rail Damage Assessment

Assess vertical displacement, Cant, Twist (both short base and long base).

Embedded Wall Excavations 

Embedded wall excavations are modeled in plan as polygons, with a level at each corner or circular vertical shafts. Each is assigned horizontal and vertical ground movement curves that are used to calculate soil settlements and horizontal ground displacements both at and beneath the surface.

You can use this option for the construction of retaining walls and for excavation in front of such walls to form restrained cuts or basements.

Xdisp for Tunnels and Mines

Tunnels can be modelled as cylindrical excavations in soil.  XDisp software defines the settlement profile at the surface or specified depth based on estimated volume loss above the tunnel due to deformation. This method is based on empirical results and is much quicker and simpler than 3D FE.

Mines are taken as excavations of rectangular cross-sections in rock. XDisp uses an analysis based on the stochastic influence approach to predict subsidence and horizontal displacement.
