铁路节能环保与安全卫生

以高速铁路全封闭声屏障工程为研究对象，将BIM技术与3D PDF、CATIA Composer工具深度融合，围绕BIM设计与数据结构、三维可视化技术交底体系及施工过程模拟方法展开系统性研究。研究成果包括：构建“项目—工点—构件”三级数据结构体系，实现全生命周期数据的规范化管理；研发轻量化交互式交底技术，提升信息传递的准确性与效率；建立BIM模型与施工进度耦合的4D模拟方法，优化施工方案制订。该成果为复杂结构声屏障建设及运营期全生命周期数字化管理提供关键技术支撑。

Taking the fully enclosed noise barrier project of high-speed railway as the research object, deeply integrating BIM technology with 3D PDF and CATIA Composer tools, BIM design and data structure construction, 3D visualization technical disclosure system, and construction process simulation methods are researched systematically. The research results include: constructing a three-level data structure system of "project-work sitecomponent" to realize standardized management of full life cycle data; developing lightweight interactive disclosure technology to improve the accuracy and efficiency of information transmission; establishing a 4D simulation method coupling BIM model with construction schedule to optimize construction scheme formulation. The results provide key technical support for the full life cycle digital management of complex structure noise barrier construction and operation periods.
