GEO5
Ground Loss
This program is used for analysis and determination of the shape of subsidence trough above excavations and to evaluate the damage to buildings situated in the affected area.
Main features
- Subsidence trough analysis using the Volume Loss Method or classical theories (Peck, Limanov, Fazekas)
- Shape of subsidence trough estimated using Gauss or Aversin approximation
- Can model sequential excavation and multiple tunnel tubes
- Determination of subsidence trough shape, settlement, gradient and horizontal strains
- Subsidence trough analysis at ground surface or at given depth
- Consideration of layered geological profile when using traditional methods
- Implemented table with recommended values of VL and k when using the Volume Loss Method
- Assessment of building damage
Building damage due to tunnelling
Considerable experience with a number of shallow tunnels excavated below built-up areas allowed the elaboration of the relationship between the shape of the subsidence trough and the damage to buildings in overburden areas. The program predicts ground movements with such precision that it is now possible to use the results to estimate financial compensation for damage induced by tunneling. Its accuracy is sufficient for the preparation of contract documents and for use by contractors bidding for tunnel construction.
The program offers four types of building damage determination:
- Evaluation of tensile failure
- Evaluation of failure due to trough gradient
- Evaluation of a relative deflection of buildings (hogging, sagging)
- Evaluation of selected section of a building
Fine Limited co-operated on development of this program with Radko Bucek MSc., Ph.D., who is a distinguished expert in the field of underground structures. He gained his considerable experience whilst working with world-known consultant companies such as Golder Associates, SG-Geotechnika and D2-Consult. He now works as the Chief Tunnel Engineer for Mott MacDonald Prague.

I use wide scale of programs in different language versions for foreign contracts. I appreciate the possibilities of calculation according to various foreign standards.
Thanks to GEO5 I can propose, test and decide optimal solutions to complex geotechnical problems based on several approaches and hypotheses, thanks to its versatility, simplicity and step by step analysis. The technical service is at the height of the best, being professionals with deep knowledge in the subjects that treat the programs.
It’s really great how easy the software is. I’m now doing the calculations so much faster and easier than doing it manually and most importantly, the technical customer service team are great and they respond instantly and professionally to any question or clarification. Thank you guys for being so awesome. High fives!
