摘　　要：为推进铁路工程建设信息化发展,铁路设计行业大力推进BIM技术研究。通过对现阶段铁路站前专业BIM技术应用实例和路基二维辅助设计方法的广泛调研,提出一种基于运用自主研发的三维铁路路基辅助设计软件的建模方法,结合川藏线拉林段路基区间,完成建模流程和设计成果的展示。实践表明,三维设计有助于设计人员更为全面直观了解实际工程结构,新增可视化效果,提高设计精确性,为铁路路基设计行业带来新的设计理念和运用基础。In order to promote the informatization of railway engineering construction, researches on BIMtechnology are conducted extensively by railway design institutes. A modeling method is proposed basedon self-developed three-dimensional design software for railway subgrade in the light of the BIM-basedmodeling process and extensive investigations in the railway from Lasha to Linzhi. The practices show thatthe three-dimensional design helps designers to understand the practical engineering structurecomprehensively with additional visual effects, and improves design accuracy, which brings about a newdesign idea and lays applicable foundation for railway subgrade design.
