基于3D WebGIS的土木水利工程BIM集成和管理研究

摘要

针对目前BIM与GIS主流集成方案中的不足,提出基于3D WebGIS的BIM数据集成和管理方案.该方法主要采用WebGL作为集成容器,基于网络服务接口传输数据,结合集成中的关键技术实现了GIS中IFC模型数据的分级集成.根据上述方法,提出了面向土木水利工程的BIM与GIS原型系统的框架,并结合网络编程知识,以开源工具为基础,实现了BIM数据在GIS环境下的快速、高效集成,为工程全生命周期的应用提供了支持环境.测试示例数据验证表明,该方法具有可行性和适用性,在土木水利工程领域具有较大的应用价值.%In view of the current shortage in the mainstream integration scheme of BIM and GIS,a BIM data integration and management scheme based on 3D WebGIS is proposed.This method mainly uses WebGL as integrated container,transfers data based on the web service interface,and combines the key technologies to realize the hierarchical integration of IFC model data in GIS environment.According to the above methods,the framework of BIM and GIS prototype system for civil and hydraulic projects is proposed.And based on the knowledge of web programming and the open source tools,the BIM data is integrated in the GIS environment quickly and efficiently,providing a supportive environment for the lifecycle application of engineering.Then the feasibility and applicability of the prototype system are verified through sample data,which shows that it can be widely applied in the field of civil and hydraulic engineering.
