V PRODUCT LIABILITY
Rockfall, slipping, landslides, and avalanches are sporadic and unpredictable. The cause can vary, ranging from
human activity (buildings, etc.) through to force majeure (weather, earthquakes, etc.). The diverse range of trig-
gers of such events make it impossible to use a scientific approach to guarantee the safety of people and material
assets.
Suitable engineering calculations using predictable parameters and the appropriate production of fault-free pro-
tective measures in specific risk zones do, however, reduce the risk of injury and the loss of material assets con-
siderably.
The monitoring and maintenance of such systems are absolutely necessary to guarantee the desired safety lev-
els. This may also be reduced by events, natural disasters, an insufficient dimensioning basis, or non-usage of
standard components, systems, or original parts, but also by corrosion (caused by environmental pollution or oth-
er human factors, as well as other external influences).
The 1:1 rockfall tests test a very intense load fall but only actually show a standardized situation; however, the
lay-outs and designs of the structures used in the field may differ greatly due to the topography of the terrain. It is
not always possible to determine the influence of such modifications and adjustments precisely. Critical aspects
are, for example, post spacing, changes in alignment, rope anchor installation angles, as well as the direction and
speed of rock impact.
Geobrugg can help in protecting against the influences of greater deviations from the standard and specific situa-
tions and provide suggestions for feasible solutions. However, Geobrugg cannot guarantee behavior that will be
the same as in the 1:1 rockfall tests. In critical cases, reinforcing individual components with respect to the stand-
ard barrier is advisable.
