摘　　要：铁路线路防护栅栏和安全保护区设计是铁路设计的重要内容,但国内一直缺乏相应的辅助设计软件,导致设计效率较低,工程数量计算不准确,设计质量不可靠。在此前提下,文章以中铁二院"铁路线路防护栅栏和安全保护区辅助设计系统"为研究背景,分析系统采用的功能结构,并从数字地面建模及应用、铁路线路中线计算模型、设计实体多级关联、防护栅栏纵断面自动设计、设计成果输出等5个方面总结了研发软件的关键技术,采用ObjectArx二次开发技术研发了软件,并在个别项目中应用,表明软件具有如下显著特点:①与现行铁路线路设计软件无缝集成;②设计实体相互关联,保证了设计的方便性和数据一致性;③实现线路防护栅栏纵断面设计自动化,较大地提高了设计效率和质量;④设计达到精细化水平。The design of protection fence and safety protection area on the railway line is an important part in the design of the railway, but the lack of corresponding aided desigh software in China leads to lower design efficiency, inaccurate calculation of work quantities and unreliable design quality. The paper, taking the CREEC＇s computer aided design sys- tem for protection fence and safety protection area on the railway as research background, has analyzed functional struc- ture of the system, and summarized the five key technologies for R＆D software from digital terrain modeling and applica- tion, railway central line calculation model, multi-level association of design entities, automatic design of protective fence profile, output of design results. An calculation software has been developed with ObjectArx and applied in some projects and the application result shows that the software has the following features： ① seamless integration with the railway route design software; ② correlation of design entities, it ensures the convenience of design and consistency of data ; ③realization of automatic design of the protective fence profile, it will greatly improve design efficiency and quali- ty; ④refining design.
