摘要
地下管线的拆迁和改移是城市轨道交通线路规划设计需要考虑的重点问题之一。针对传统二维管线存在显示效果不直观、空间关系不明晰、与地上城市三维模型不能衔接一致等问题,采用InfraWorks和Civil 3D BIM平台及二次开发技术,提出了一种BIM协同的城市地下管网三维快速建模方法,较好地解决了地下管线三维建模与城市三维模型有效衔接一致问题,以三维实体管线模型真实的反映了城市三维场景下的地下管网复杂空间分布状态,为城市地下管网三维快速建模、管线拆迁和改移量计算提供了新思路和解决方案。
One of the key issues that need to be considered in the planning and design of urban rail transit lines is the demolition and relocation of underground pipelines. The traditional two-dimensional pipelines have problems such as unintuitive display effects, unclear spatial relationships, and inconsistent connection with the ground urban three-dimensional model. Aiming at these problems, InfraWorks and Civil 3D(three-dimensional) BIM platform were adopted. A rapid 3D modeling method for the urban underground pipeline network with the BIM cooperation is proposed to well solve the problem of the effective connection of 3D modeling of the underground pipelines and the city.The 3 D modeling method of underground pipe network was achieved to truly reflect the complex spatial distribution status of the underground pipeline network. It provides a new idea and solutions for the rapid modeling and the amount calculation of the demolition and relocation of pipelines.
