RANGE OF APPLICATION
The engineering of rockfall protection systems is based on detailed investigations by specialist engineering com-
panies, which take the following geotechnical aspects in particular into account to define the range of applications:
•
Previous rockfall events
•
Condition of the rockfall breakout zone
•
Assessment of the stability of the entire rockfall zone
•
Frequency of rockfall
•
Size of the rocks to be caught
•
Trajectories and bounce heights of the rocks
•
Calculations of the kinetic energy
•
Barrier position (taking the local topography into account)
•
Anchoring conditions
II QUALITY OF THE INDIVIDUAL SYSTEM COMPONENTS
Geobrugg AG, formerly the Geobrugg Protection Systems division of Fatzer AG, Romanshorn, Switzerland, has
been certified with registration number CH-34372 in accordance with the quality management system require-
ments (ISO 9001:2008) since August 22, 1995. The certification body is the SQS (Swiss Association for Quality
and Management Systems), which belongs to IQNet. The quality manual provides a complete specification re-
garding how the individual system components (primary materials, third-party products, and finished products) are
to be comprehensively tested in order to rule out any deficiencies in quality. The relevant certificates can be found
in the appendix.
III FUNCTIONAL RELIABILITY OF THE BARRIER SYSTEMS
The system's functional reliability is based on 1:1 rockfall tests, performed and tested in accordance with Europe-
an Technical Approval Guideline ETAG 027 "Falling Rock Protection Kits" and Swiss Guideline (FOEN) in Wa-
lenstadt, SG (Switzerland). The 1:1 rockfall tests involve performing vertical impacts into the middle field of a
three-field barrier, where the posts are spaced at 10 m and an impact speed of at least 25 m/s is reached. The
tests are accepted by a notified body and receive an approval, known as an ETA (European Technical Approval).
The approval no. of the GBE-3000A system is ETA
– 10/0084.
IV QUALITY CONTROL FOR INSTALLATION
This system manual provides a detailed description of how to design and install the barrier.
