Abstract

The chain fence (12), as a dynamic barrier to restrain rock avalanches, is composed of a number of interlaced circular rings (30-44) so that each ring is interlaced with at least four other neighboring rings. Each ring is formed of a cable with a number of twisted strands, shaped into rings with a diameter of 200-600 mm. The cables for the rings are of metal or polymer materials.
