摘　　要：针对铁路桥梁结构复杂、反复修改和多样化的BIM建模要求,单纯利用建模软件手工建模方法已不能很好满足这些要求。通过对桥梁结构分解、参数分析和各部件的数据结构设计,采用数据库实现了桥梁和细分部件参数的管理和编辑。利用BIM API二次技术和.Net编程语言,研发了基于BIM的铁路桥梁三维建模系统,实现了自动化、参数化和批量化的铁路桥梁BIM模型快速创建,解决了桥梁模型快速拼装和精准定位问题,有效提高了建模效率,研究方法具有较好的适应性。The characteristics of railway bridges are complex and diverse,so the bridge BIM modeling requires repeated modification and diversification,the manual modeling methods which using modeling software alone cannot meet these requirements well.On the basis of bridge structure decomposition,parameter analysis and data structure design of each component,the paper used database to manage and edit parameters of bridge and subdivision components.By using BIM API secondary technology and.Net programming language,a three-dimensional modeling system of railway bridge based on BIM was developed,which realized the rapid creation of automatic,parametric and batch BIM model of railway bridge.It solves the problems of rapid assembly and precise positioning of bridge model,effectively improves the modeling efficiency,and the research method has good adaptability.
