Geobrugg | World record 2017 - 25 metric tons 103 km/h rockfall impact stopped! @geobrugg | Uploaded October 2017 | Updated October 2024, 3 hours ago.
October 16th, 2017: A 25-ton concrete block is thrown onto a rockfall protection barrier at the Geobrugg test site. The 30-meter-long and 7-meter-high net is installed vertically on a rock wall. The block with the weight of a heavy truck is released at a height of 42 meters and accelerates to 103 km/h. With a loud crash, it falls into the center of the net, which successfully stops the impact. This represents a world record. The magic mark of 10,000 kilojoules of impact energy in rockfall protection has been broken. Thus, Geobrugg's engineers have set a milestone in the mitigation of natural hazards.
This video shows the making of the world record.
2017 benchmark data:
- Free falling 43 m = 103 km/h
- Impact energy 10000 kJ
- 8.15 meters barrier deflection
- 67 % residual barrier height
