摘要研究目的:落石作为一种常见的地质灾害形式，严重威胁着铁路建设与运营安全，因此科学合理的开展落石设计成为减少此类地质灾害的重要手段之-。国际上在落石防治方面已形成包括危岩勘察、稳定性评价、落石运动路径及能量计算、被动防护网设置位置确定、防护网选型等内容的基本健全的设计体系。而国内设计体系尚不完善，缺乏为设计提供落石轨迹与冲击能量计算的软件，因此开发-套具有自主知识产权的分, 析软件势在必行。

研究结论:(1)RFA软件可在设定范围内采用随机概率的形式对落石运动轨迹、落点位置、冲击能量范围等进行计算，计算结果可直接作为设计依据;( 2 ) RFA软件大大提高了目前铁路行业的落石计算能力与工作效率;(3)RFA软件已成功应用于东科岭隧道出口段落石设计中，并取得良好效果，今后可在该领域中推广使用。

Abstract：Research purposes ; As one of the common forms of geological disasters，rockfall is a serious threat to the railway construction and operation safety，so the development of scientific and reasonable design of rockfall becomes one of the important means to reduce the geological disasters. In the aspect of prevention rockfall has formed including survey，stability evaluation，and rock fall motion path and energy calculation，determent the passive fence position setting, selecting the model of defending net internationally，etc. But design system is not perfect in China, software for rockfall trajectory and impact energy calculation is lacked, so developing a software with independent intellectual property rights is imperative.
Research conclusions:(1)Using a random probability within a set range，RFA software can calculate the rockfall trajectory, landing position，the impact energy range and so on. The results can be directly used as the design basis. (2)RFA software can greatly improve rockfall calculation capabilities and work efficiency on the current railway industry.(3)RFA software has been successfully applied to the Dongkeling tunnel exit passages stone design, and achieved good results. It can be used wildly in this field in the future.
