Geo-Engineering Design

LYNX geo-engineering design provides a 3D geoscience platform for interactive design, planning and survey of surface and underground excavations and subsurface engineering structures. It includes a range of design options that facilitate development of complex excavation geometries for a wide variety of design conditions.
Interactive 3D Design Tools
  • viewplane sections at any orientation, controlled by real-world coordinates and azimuth / inclination / scale parameters.
  • background displays of any combination of geoscience and/or engineering data structures in a wide range of display formats for design reference purposes.
  • interactive boundary definition of excavation profiles and assignment of engineering parameters for planning purposes.
  • boundary snapping and selection from any geoscience or engineering source in the background display.
  • 3D linking of boundaries to form excavation volumes.
  • interactive 3D editing of excavation boundaries into complex irregular shapes.
  • template facilities for definition, positioning, scaling and rotation of standard excavation profiles.
  • assembly facilities for replicating and positioning standard excavation units.
  • wild-card grouping of excavation volumes to define planning units.
  • interactive sectioning at any viewplane orientation through defined excavation volumes.

Advanced volume modeling technology and interactive viewplane manipulation provide an efficient 3D platform for geo-engineering design of excavations and other subsurface structures. Design is performed against a background reference of relevant geoscience information .... using interactive graphics tools and excavation design techniques. The inherent flexibility of the underlying 3D modeling technology allows design and representation of complex subsurface structures in terms of surfaces, irregular 3D shapes, uniform profile shapes or combinations thereof.

Surface-Based Design Tools
  • surface data tools including contouring, thinning, clipping, merging and coordinate transformation.

  • TIN surface modeling for generation of triangulated topologies at any 3D orientation.

  • TIN manipulation tools for generation of engineering surface and thickness parameters.

  • engineering surface modeling by assignment of nominal thickness for representation of cut-off walls, drainage layers, etc.

  • excavation volume modeling of variable thickness engineering structures by auto-generation of volume elements between TIN surfaces.

Centerline-Based Design Tools
  • centerline definition for tunnels, ramps and other uniform profile excavations.
  • interactive grade / elevation design for precise centerline alignment.
  • auto-generation of volume elements along a centerline with offset and interval control.
  • curve, straight and vertical tools for auto-generation of volume elements for excavations with specified geometries.
  • profile definition for rectangular, arched and circular excavation profiles.
Tunnel and ramp design with variable grade, elevation and profile is simplified by a range of interactive centerline-based design tools.


All design tools incorporate the full LYNX interactive graphics functionality including point-and-click selection, snap-to functions, and zoom, scale and refresh functions.

Conical Expansion (Benched) Design
  • interactive definition and editing of excavation profiles.

  • slope and berm control by excavation sector and between elevation limits.

  • auto-projection of profiles between elevation limits and/or geological surfaces.

  • geological / topographical control of profile projection.

  • interactive profile editing at any design stage.

  • top-down or bottom-up design flexibility to allow either excavation or dump / fill design.

Excavation Analysis

  • 2D/3D visualization of excavation volumes and subsurface engineering structures on viewplane sections or in 3D perspective views, with options for viewing color-mapped project variables or geological intersections.

  • excavation volume reporting of any wild-card selection of excavation volumes or planning units.

  • excavation intersection reporting of the characteristic and variable values intersected by any wild-card selection of excavation volumes or planning units, and their associated volumes.

Excavation Control

Geo-engineering design provides a platform for planning and construction control of large excavations, particularly for subsurface conditions involving rapid variation of excavation materials and geotechnical / stability parameters. Since all design and subsurface characterization information is referenced by real-world 3D coordinates it relates directly to the construction process.
