本研究使用的数值计算程序，以前验证的数据，从全面的实验，调查的性能修改后的原型钢丝绳围栏，以提供保护，防止落石。降低成本的修改是增加后间距和更少的铁丝网层。数值计算过程提供了各种冲击条件下的原型的非线性响应和洞察每个组件的作用，消散冲击能量。提出了一种简单而有效的提高栅栏容量的方法。最后，使用两个单位的原型，以保护一个广泛的区域进行了研究，采用的数值方法。
This study uses a numerical procedure, previously validated with data from full-scale experiments, to investigate the performance of a modified prototype wire-rope fence to provide protection against rockfall. The cost-reducing modifications are increased post spacing and fewer wire netting layers. The numerical procedure provides the nonlinear response of the prototype under various impact conditions and insights into each component’s role in dissipating impact energy. A simple but effective method to increase fence capacity is also developed. Finally, the use of two units of the prototype to protect a wide area is investigated employing the numerical procedure.
