石太线危岩落石病害地段经常有危石坠落至线路，严重威胁行车安全。通过综合比较各种整治危岩落石的工程措施，最终确定因地制宜的安设高强度金属柔性防护网进行病害整治。并通过对一处典型病害工点进行三维激光扫描、落石轨迹模拟分析、落石最大速度和动能计算等研究，详细阐述金属柔性防护网的合理选型以及防护方案确定的方法。
石太線危巖落石病害地段經常有危石墜落至線路，嚴重威脅行車安全。通過綜閤比較各種整治危巖落石的工程措施，最終確定因地製宜的安設高彊度金屬柔性防護網進行病害整治。併通過對一處典型病害工點進行三維激光掃描、落石軌跡模擬分析、落石最大速度和動能計算等研究，詳細闡述金屬柔性防護網的閤理選型以及防護方案確定的方法。

In the perilous rocks and falling rocks zones along Shijiazhuang-Taiyuan Railway, there are often perilous rocks falling to the railway line, posing a threat to the operation safety of railway. For this reason, by comparison with various treatment measures of perilous rocks and falling rocks, and by adjusting measures to local condition, the flexible metal safety netting system ( SNS) was employed to resist the falling rocks. Furthermore, in combination with the research for a typical rock-falling worksite on several issues such as three-dimensional laser scanning, simulation analysis of falling rock's trace, calculation of maximum velocity and kinetic energy of falling rocks, etc. , the paper illustrated how to reasonably select the SNS and how to determine the protection scheme.
