基于Autodesk的堤坝BIM模型构建与信息化框架开发与应用

Development and application of Autodesk-based dike' s BIM modelling and information framework

为了解决现有技术下的堤坝BIM三维线框模型缺陷,根据堤坝工程的特点及其模型构建需求,建立了堤坝BIM模型构建与信息化框架。该框架包含堤坝工程的编码标准、命名体系、断面提取功能与三维实体生成功能等内容,可将几何模型与属性信息自动融合为实体BIM模型。该框架能在不同BIM软件平台下实施,选取Autodesk平台的Civil 3D与Revit进行. Net二次开发,在相关工程中进行了实践,成功构建了BIM模型,提高了工作效率,对堤坝工程的BIM全流程应用具有参考意义。

In order to solve the technology defects in current dike’s BIM 3D wireframe-modelling method,the dike’s BIM modelling and information framework is proposed based on the characteristics of dike and its modelling needs.It consists of code standard module,naming system,section extraction module and 3D solid modelling module.With the help of such framework,the geometry and corresponding information can be ironed into the same solid BIM model.Autodesk and its subsidiary Civil/3D Revit are utilized to implement the above framework,while it can also survive in different BIM software platforms.The application results show it can construct the BIM model automatically,which enhances work efficiency profoundly.Moreover,it has a reference significance for the dike’s life-cycle BIM application.
