基于正向BIM的工程勘察CAD软件研究

Research on engineering survey CAD software based on forward BIM

目前,勘察行业常用的CAD软件产品大多起源于上世纪90年代,只着眼于提高单向工作的效率,而在协同工作、信息共享方面,具有很大的局限性。因此,基于BIM理念进行重构是十分必要的。本文简要介绍了新一代正向勘察BIM软件的基本理念、架构和特点,探讨了软件在解决三维连层、地质建模、报告编制、协同工作、信息共享等关键问题上的思路,并结合工程实例对软件的工作模式、效率、质量进行了验证。

At present,most of CAD software products commonly used in the survey industry originated form the 1990 s, focusing on improving the efficiency of one-way work. It has great limitations in collaborative work,such as information sharing. Therefore,it is necessary to be reconstructed base on BIM concept. This paper briefly introduces the basic concept,architecture and characteristics of the new generation of forward BIM software for investigation,and discusses the ideas of the software in solving the key problems,such as 3 D layer connection,geological modeling,report preparation,collaborative work,information sharing,and so on. Combined with the engineering example,the working mode,efficiency and quality of the software are verified.
