基于三维实景的婺江大桥CIM正向设计应用

Based on the forward design application of CIM of three-dimensional Wujiang Bridge

本文结合实际三维实景大桥-婺江大桥实现了CIM(计算机集成制造)在全标段、多桥型项目中的综合应用。首先结合了大地坐标系定义项目的实际位置,在线加载项目实际位置的三维地形和影像映射,观察所建模型与实际地形的契合度。进一步的,进行以及引桥不同位置的建模,构建了三维模型,并进行正向设计应用。本文内容涉及了CIM绝大多数的桥梁设计功能,可为类似设计研究提供参考。

Combined with the actual three-dimensional real-world bridge-Wujiang Bridge,the comprehensive application of CIM in the whole bid section and multi-bridge project is realized.Firstly,the geodetic coordinate system is combined to define the actual location of the project,and the 3D terrain and image map of the actual location of the project are loaded online to observe the fit between the model and the actual terrain.Furthermore,the 3D model was constructed and the forward design application was carried out by modeling the different positions of the approach bridge.This article covers most of the bridge design functions of CIM,which can provide a reference for similar design research.
