摘　　要：城市地下环境复杂多样,存在各种地质条件、地下设施和地下管线网络,管线排布难度较大,为此提出了一种基于BIM的城市地下管线分段排布方法。根据三维空间中的坐标与属性信息,计算地下区域空间关系,得到地下管线分段排布的安全距离。采用BIM构建城市地下管线模型,转换局部坐标,获得管线表面的三角形不规则网络表达。将地下管线网络信息导入BIM软件中,创建一个三维模型,通过空间定位,形状建模,属性设置,关联性建立实现城市地下管线分段排布,并通过BIM模型展示排布的可视化结果。通过实验证明所提方法能够较好的分段排布城市地下管线,线路规划合理,方便后期管理检修。Generally,the urban underground environment is complex and diverse,with various geological conditions,underground facilities,and underground pipelines,making pipeline layout difficult.Therefore,this paper presented a method of segmented layout for urban underground pipelines based on BIM.Firstly,we used the coordinates and attribute information in three-dimensional space to calculate the spatial relationship between underground areas,thus obtaining a safe distance for the segmented layout of underground pipelines.Secondly,we built a model of urban underground pipelines by using BIM.After converting local coordinates,we got a triangular irregular network representation of the pipeline surface.Moreover,we imported the network information of underground pipelines into BIM software,and then constructed a 3D model.Finally,we achieved the segmented layout of urban underground pipelines through spatial positioning,shape modeling,attribute setting,and correlation establishment.Meanwhile,we displayed the visualization results of the layout through the BIM model.Experiment results prove that the proposed method is effective in the segmented layout of urban underground pipelines,with reasonable route planning and convenient management and maintenance in the later stage.
