Collaborative design of complex overpass based on BIM technology

为了促进BIM技术在桥梁工程中的推广,研究了BIM技术在复杂立交桥设计阶段的应用.利用软件Revit Structure建立立交桥的构件族库,运用Civil 3D对立交桥整体选线进行规划,并利用Dynamo软件对异形匝道参数进行设计,运用三个软件建立复杂立交桥完整的数据信息模型,从而探索BIM技术在立交桥初步设计优化时所发挥的作用.结果表明,BIM技术可将复杂、抽象的二维桥梁平面图描述成细致、直观的三维桥梁模型,可实现对桥梁设计图纸的深度优化. BIM技术可在桥梁工程全周期运营中得到应用,并且作为标本进行推广,拓宽了桥梁工程管理的应用方法.

In order to promote the generalization of BIM technology in bridge engineering,the application of BIM technology in the design stage of complex overpass was studied.The library family of overpass was established with the software Revit Structure,the overall route selection of overpass was planned with the software Civil 3D,and the heteromorphic ramp parameters were designed with the Dynamo software.In addition,the complete data information model of complex overpass was established with three softwares to explore the function of BIM technology in the preliminary design optimization of overpass.The results show that the complex and abstract two-dimensional bridge plane graph can be described as a detailed and intuitive three-dimensional bridge model with the BIM technology,and the deep optimization of bridge design drawing can be realized.The BIM technology can be applied in the full cycle operation of bridge engineering,and can be generalized as a sample,which widens the application method of bridge engineering management.
