Deformation Monitoring NATM

NRG software supports NATM tunnelling requirements

The deformation monitoring solution provided by NRG also supports NATM (New Austrian Tunnelling Method) tunnelling requirements.

Tunnel profile survey data be entered manually or imported from coordinate or observation files.

When monitoring data is imported the points are matched by name or by radial distance to the base points and the data is given a time stamp.

Display trendlines of movement-time and fish tails

Visually that data can be viewed in plan, cross section, elevation, vector/time graphs, vertical/time graphs, horizontal/time graphs, epoch and by isopachs. Current excavation steps can be viewed so that the direct effects of the works can be reviewed.

Sections can be taken through monitoring data, along the design alignment to produce tunnel profile sections. A shape editor is included in which you can enter the tunnel design profile and specify points and subsequent lines for monitoring convergence.

A variety of report options are available including cross sections and long sections which can display trendlines of movement/time and fish tails.
