Abstract (en)

[origin: EP0877122A1] The barrier for stopping and absorbing the energy of falling rocks comprises a net (10) located between two posts anchored in the ground. It is held by carrying cables (14) connecting the posts to support plates (18) anchored in the ground. A fusible cable has a reduced elasticity and a modulus of elasticity less than the carrying cable. This cable has at each end locking device connecting the fusible and carrying cable assembly so that at rest the length of the fusible cable between the locking device is less than the length of the carrying cable. Each of the locking device lock the fusible cable on the carrying cable after the latter has been subjected to a traction force due to the fall of rocks. The fusible cable subsequently undergoes a traction force along its length following which it ruptures.
