既有公路BIM模型构件拆分编码与三维模型建立研究

Research on Component Splitting,Coding and Three-dimensional Model Establishment of Existing Highway BIM Model

研究针对既有公路BIM建模问题,文中明确了既有公路BIM模型拆分原则,给出了拆分结果;同时从公路养护阶段BIM应用的实际需求出发,将构件编码结构从5层扩展到6层,以满足既有公路模型构件拆分结果的要求,并结合对目前主流的BIM建模软件的比较筛选,总结提炼了一套专门针对既有公路BIM建模的总体思路;最后依托实体工程,具体阐述了既有公路BIM建模的全部过程。

The research is aimed at solving the problem of BIM modeling of existing highways.Firstly,the principle of splitting BIM model of existing highways is defined,and the results of splitting are given in the study.Then,from the actual requirements of BIM application in highway maintenance phase,the component coding structure is extended from five layers to six,which is to meet the requirements of the splitting results of the existing public model components.Next,combined with comparison and screening of the current mainstream BIM modeling software,a set of general ideas for the existing highway BIM modeling is summed up.Finally,the research specifically describes the entire process of BIM modeling of existing highways relying on the engineering entity.
