BIM+GIS技术在高速公路临建工程中的应用

为提高临建工程设计效率,以玉楚高速公路土建11标临建工程为依托,通过卫星地形与卫星影像建立三维GIS模型,结合线路的走向和红线用地情况,基于GIS模型进行面域、高差及坡度分析,筛选拟选临建工程区域,结合临建工程建设标准,定义出红线范围;利用BIM技术开展三维正向设计,并将其BIM模型与GIS模型整合,指导现场实施。

Application of BIM+GIS Technology in Expressway Temporary Construction

In order to improve the design efficiency of temporary construction projects, relying on the temporary construction project of Yuxi—Chuxing expressway civil engineering section 11, a 3D GIS model is established by satellite terrain and satellite images to analyze the area, elevation difference and slope based on the GIS model in combination with the route trend and red line land use, screen the proposed temporary construction areas, define the red line range in combination with the construction standards of temporary construction projects. This paper uses BIM technology to carry out three-dimensional positive design, and integrate its BIM model with GIS model, and guide the on-site implementation.
