基于OpenCascade和数据实体技术的数字化桥梁设计软件

摘要

针对桥梁设计的特点以及行业存在的问题与需求，基于OpenCascade这一平台，采用目前工程CAD中较为前沿的技术——“数据变量驱动图形设计技术”构建桥梁的三维信息模型，北京交科公路勘察设计研究院有限公司自主研发了“基于OpenCascade图形技术和数据实体技术的数字化桥梁设计软件”。本文重点介绍了该软件的创新点及主要功能。%According to the characteristics of bridge design and the existing problems of Highway traffic industry, based on Open Cascade graphics technology, using data variables driving graphic design technology which is the advanced technology in current engineering CAD to construct the 3 D bridge information model, RIOH Transport Consultants Ltd. independently develops ＂the digital bridge design software based on Open Cascade graphics tech- nology and data entity technology＂. This paper emphatically introduces the characteristics, functions and innovations of the software.
