Application of Autodesk Civil 3d and GIS Data in Angola Railway Preliminary Design

在安哥拉某铁路初步设计过程中,通过结合使用Autodesk Civil 3d软件与GIS数据协同设计施工,可以有效减少前期投入,提高工作效率。本文以安哥拉某铁路初步设计为例,结合软件协同设计施工,从GIS数据获取、地形曲面生成、铁路平纵断面布置、土方工程量计算等方面介绍Autodesk Civil 3d软件与GIS数据在海外铁路设计中的应用,为缺乏现场实测数据的铁路初步设计提供了经济、高效的解决方案,也为进一步的现场考察、深化设计和现场施工提供了方向和依据。

In the preliminary design process of a railway project in Angola,the integrated application of Autodesk Civil 3 d and GIS data has reduced the cost and improved the design efficiency. This article takes the preliminary design of a railway project in Angola as an example to introduce the application of Autodesk Civil 3 d software and GIS data in overseas railway design. The aspects of GIS data acquisition,terrain surface generation,railway horizontal and vertical section layout,and earthwork calculation are shown in this paper. It provides an economical and efficient solution for the preliminary railway design lacking on-site measured detail data,and also provides a guide and basis for further on-site inspection,design and construction.
