Proposal of a High Energy Rockfall Protection Fence With a Double-Blocking Surface and Verification on the Capture Performance

Key Points

• This research proposes a new high energy absorption rockfall protection fence and verifies its capture performance through experiments and numerical analysis.
• Conducted large-scale experiments to test the proposed rockfall protection fence.
• Performed numerical simulations to analyze responses across various drop locations.
• Compared the new design's effectiveness against traditional protection methods.
• The new fence design effectively absorbs impact energy of up to 500 kJ.
• Demonstrated enhanced performance even in areas without wire ropes due to the double-blocking surface.
• Improved construction and cost-effectiveness over traditional designs.
