GUARD SURFACE STRUCTURE

There is provided a guard surface structure excellent in shock-absorbing effect due to an unprecedented structure formed by combining a deformable supporting surface and shock-absorbing members. A guard surface structure comprises a net body 4 supported by support posts 3, such net body 4 comprising a wire mesh 11, and being deformable and provided with shock-absorbing bags 21 filled with sands. By combining the deformable net body 4 and the shock-absorbing bags 21, a force of impact due to rockfall or the like can be effectively absorbed due to deformation behaviors of the shock-absorbing bags 21 and the net body 4. In this case, sands inside the shock-absorbing bags 21 are caused to move when subjected to the force of impact, thereby allowing the shock-absorbing bags 21 to deform and thus absorb the force of impact. Further, the net body 4 deforms after the force of impact has been first applied to the shock-absorbing bags 21, thus allowing the net body 4 to deform less. Furthermore, since the net body 4 is provided between the support posts 3, 3 . . . , a shock-absorbing effect of a guard fence can be improved.
