Rockfall tests in the field
Steinschlagversuche

Repeated controlled rockfall tests in the field provide data for a statistical analysis of the rockfall trajectories.

Semi-automatic determination of rockfall trajectories
Semi-automatic determination of rockfall trajectories

Understanding and predicting the path (trajectory) of individual rockfalls is of crucial importance for designing protection measures and hazard maps. Unfortunately, our ability to observe trajectories is still very limited. Traditionally, this is done using video analysis (2D & 3D) that requires an unobstructed view of the moving rock and constrains the measurement area to the field of view of the cameras. We now want to explore a new technology to measure trajectories of falling rocks using an instrumented boulder and a local positioning system (LPS).

Project Tree Stability
Tree stability

The public accounts of swiss forests as protective shelter against natural hazards amounts to milliards of swiss francs per annum. What is actually the mechanical resistance of forest stands against natural hazards?

Numerical modeling and design of flexible debris flow barriers
Flexible debris flow barriers

A new load model describes the interaction between a debris flow and a flexible protection barrier. Compared to similar barriers against rockfalls with a well-known load due to the rigid behaviour of the rock, the loads submitted by a debris flow are quite unknown, neither in Switzerland nor worldwide. An extensive experimental programme with full-size and laboratory dynamic tests delivers the needed information for proper simulation models.

Rockfall Attenuator Systems: Kinetic Energy Dissipation and Guidance of Rockfalls
KTI Attenuators

Differing from standard rockfall barriers, rockfall attenuator systems intercept a rockfall trajectory guiding it under a tail drape, its kinetic energy is then dissipated through net deformations and interaction with the slope. Rockfall can then be contained at the base of slope avoiding maintenance and clean out costs commonly associated with standard rockfall barriers.

Mechanics of shallow landslides (Hangmuren) and interaction with flexible barriers
KTI-Hangmuren

This project aims to develop new flexible barrier technology for use as a mitigation measure against shallow landslides. The loading produced by shallow landslides differs significantly from previous applications such as rockfalls or debris flows.

Flexible rockfall protection gallery systems
KTI Galleries

Flexible high energy rockfall protection galleries: An economical and environment-friendly alternative to concrete galleries in mountain regions?

Available languages: English 

Numerical simulation of flexible rockfall protection systems
FARO

The developed software FARO enables a more efficient development or optimization of new types due to a reduced number of expensive prototype field tests. In addition, the use of software provides the possibility to simulate projected barriers considering special load cases, which cannot be reproduced in field tests, as well as special geometrical boundary conditions for individual sceneries.
