Post-processing of tunnel data

This CAD application processes tunnel surveying data measured by total stations running TcpTunnel or other programs.

TcpTunnel CAD calculates from the points and alignment the cross sections, that can be filtered and edited, and allows you to compare with the tunnel template drawn as a polyline. You can also draw profiles in single or sheet mode with multiple customization options, as well as generate the 3D model of the tunnel.

Tunnel data processing

This software, working under AutoCAD,allows to process data gathered from total stations running TcpTunnel or other programs. Every project is compound of a horizontal and vertical alignment, superelevation, templates and point files, supporting different formats.

Template Definition

Templates can be defined by parameters or selecting a polyline in AutoCAD. The distances from the center of template to alignmentand superelevation criteria must be given.It is possible to apply different templates to intervals of alignment and interpolate their dimensions.

Cross section calculation and editing

The measured cross-sections can be computed from points, giving the chainageinterval, minimum number of points, undercut and overcut tolerances, etc. For generating the cross-sections, the measured points are analized regard to hozirontal alignment of the project, supporting even spirals and alignments with crossed sections.Also with the editor are included tools for removing, adding or moving points before drawing, comparing with the theoretical tunnel template.

Cross-section drawing

It is possible to draw cross-sections inCAD, in individual mode or by sheets. There are options to label differences between project and measured cross-sections as well as station, heights, areas, etc.

Tunnel Drawing

It is possible to create a 3D view of measured cross-sections as a wireline drawing. There are options to draw measured and project cross-sections, the alignment in 3D, longitudinal lines, etc.

Volume Calculation

The program computes volumes of infra and over-excavation by comparing project and measured cross-sections. Reports can be generated and sent to printer, ASCII or HTML files and exported to Word or Excel. 3D Model. The program allows to generate a 3D triangulation of the tunnel, take a tour inside it and export to several file formats of geometrical definition, are as OBJ and OFF.
