摘要
针对山岭隧道地上地下一体化三维建模效率低、数据融合难度大的问题,提出一套基于建筑信息模型(building infor-mation modeling,BIM)+地理信息系统(geographic information system,GIS)+倾斜摄影技术的建模方法.以武汉市黄龙山隧道为例,首先,按用途和施工工序对山岭隧道构件进行分类,利用Revit和Dynamo软件,采用参数化建模+自适应拼接的方法构建隧道三维结构模型;其次,通过无人机采用倾斜摄影技术获取地表影像,构建三维实景模型;通过影像匹配和滤波技术处理点云数据,生成数字高程模型(digital elevation model,DEM),并结合钻孔数据,采用插值法和约束分区的方法构建三维地质模型;最后,基于MapGIS实现隧道结构模型、地表三维实景模型、三维地质模型的集成.所提方法可以优化模型管理方式,减少数据信息的丢失,实现隧道工程信息的集成与共享.
Abstract
A modeling method based on building information modeling(BIM)+geographic information system(GIS)+oblique photography technology was proposed to address the issues of low efficiency and difficulty in data fusion in integrated 3D modeling of mountain tunnels above and below ground.Taking the Huanglongshan Tunnel in Wuhan as an example,firstly,the mountain tunnel components were classified according to their purpose and construction process.Using Revit and Dynamo software,a three-dimensional structural model of the tunnel was constructed using parametric modeling and adaptive splicing methods.Secondly,surface images were obtained through drones,and a 3D realistic model was constructed using oblique photography technology.By using image matching and filtering techniques to process point cloud data,a digital elevation model(DEM)was generated,and combined with borehole data,a three-dimensional geological model was constructed using interpolation and constrained partitioning methods.Finally,based on MapGIS,the integration of tunnel structure model,surface 3D realistic model,and 3D geological model was achieved.The proposed method can optimize model management,reduce data loss,and achieve integration and sharing of tunnel engineering information.
