Geotechnical Monitoring

Axis3D GTM - Geotechnical Monitoring

Analysis and graphics for geotechnical measurements in tunneling

geotech2 Up-to-date results: Early detection of risks increases the safety of humans and structures.

Efficient workflows: Data structure is designed individually by the user according to project requirements.

Comprehensive graphics: Quick and easy interpretation of results by the project engineer.

Coordinate Calculation

Data Management


Coordinate Calculation Accurate trigonometric results are guaranteed by reliable adjustment routines that take refraction into account.
Easy determination of leveling results as well as the ability to include geotechnical sensor data minimize analysis effort. An intuitive user interface is the foundation for professional analysis of measurement data.
Data Management Users can manage large volumes of data individually and by project. Coordinates of deformation points; construction-phases; as well as readings from extensometer, anchor load cells, and pressure cells are stored by epoch. Clear data structures give a quick overview.
Graphics Varied, application-oriented graphical display options in 2D and 3D facilitate the interpretation of extensive data sets. Quick and easy generation of graphics provides up-to-date results and supports rapid, confident decision-making.
