Compare a designed tunnel mesh to an as-built tunnel mesh (for example, compare the design mesh to an as-built excavation mesh) to identify differences between the two. Or, compare an as-built tunnel mesh to another as-built tunnel mesh (for example, compare an as-built excavation mesh to an as-built shotcrete mesh).

Following are the basic steps for this workflow. For more detailed instructions, see Create a Tunnel Inspection Map and Compare Tunnel Meshes Using the Tunnel Inspection View.

Steps:

Commands:

1.

Use the Create Tunnel Inspection Map command to create a tunnel inspection map that allows you to compare the shapes of two tunnel meshes using the Tunnel Inspection View. You can select to compare a designed tunnel mesh to an as-built tunnel mesh (for example, compare the design mesh to an as-built excavation mesh). Or, you can select to compare an as-built tunnel mesh to another as-built tunnel mesh (for example, compare an as-built excavation mesh to an as-built shotcrete mesh).

2.

Use the Tunnel Inspection View command to view a tunnel inspection map that compares the shape of two tunnel meshes to identify differences between them. Differences between the two meshes are displayed in several different formats:

• Inspection Plan View - View the base mesh "unfolded", flattened, and overlayed with a grid of custom-sized mesh cells whose colors indicate the distance between each base mesh cell and its corresponding comparison mesh cell.
• Cross-Section View - View the deviation between the base mesh and comparison mesh at the specified station. The delta lines are color coded to indicate overbreaks and underbreaks.
• Delta View - View the delta between the base mesh and comparison mesh at the specified station in a 2D graph.

Run a customizable Microsoft® Word-based Tunnel Inspection Report or Tunnel Inspection Report (with geological overprofile) based on a tunnel inspection map that compares the shape of two tunnel meshes to identify differences between them.
