窗帘式柔性防护网的设计与应用

落石病害对铁路行车安全构成威胁。以丰沙铁路K49段珠窝东站南端的山体落石治理工程为例，针对山体落石病害常见的崩塌、滚坠落等形式，详细地分析了窗帘式柔性防护网治理落石病害的设计原理；运用RockFall软件，对落石轨迹、冲击能量、弹跳高度进行验算，论证了结构的安全性。采用窗帘式柔性防护网，对山体落石病害进行整治，取得了良好效果，确保了线路的安全营运。

The Design and Application of Curtain Type Flexible Protecting Mesh

Rockfall disaster poses a threat for the safety of the railway operation. Taking for an example the mountain rockfall control projects for the southern end of the Zhuwo East Station of K49 Segment, Fengsha Railway, falling rocks for mountain disease mainly shows the collapse, rolling fall, etc., we have analyzed in detail the design principles of using the curtain type flexible mesh to treatment the rockfall disaster; used the rockfall software to calculate the values of the rockfall trajectory, impact energy, and jumping height, and demonstrated the safety of the structure. Adopting curtain type flexible protecting mesh for the rockfall disaster treatment, we have achieved good results so as to ensure the safe operation of the railways.
