摘要
近年来,随着BIM迅速发展,各企业越发重视BIM软件研发。MicroStation是一个适合开发各类BIM软件的平台,但其缺少铁路线路、边坡、支挡、地基处理、桥梁、隧道等工程及措施对象,二次开发工具包中也未开放定义工程对象的技术。采用数据版本兼容、字符流转换读写XAttribute与ECXAttribute、分散存储与按需读取等技术,研究并提出了一种基于MicroStation的工程措施实体定义及管理方法。利用该方法可开发出一系列具备铁路专业属性、行为特征和工程关系的工程措施实体对象,并将实体有机整合,形成一套具备BIM正向设计功能的系统,从而实现基于BIM的正向设计。
With the rapid development of BIM in recent years, enterprises pay more and more attention to the research and development of BIM software. As a platform suitable for developing various kinds of BIM software, MicroStation on one hand lacks the objects needed for railway engineering-railway track, side slope,supporting & retaining structure, subgrade treatment, as well as bridge and tunnel alike, on the other it fails to open up the technology that helps to define engineering objects in its secondary development toolkit. With the application of technologies like data version compatibility, reading and writing conversion(XAttribute and ECXAttribute) of character stream, as well as distributed storage and on-demand reading, the paper proposes a MicroStation-based definition and management approaches for engineering objects & methods, which helps develop a series of railway engineering objects that are railway specific and project related. The proper integration of objects then gives rise to a BIM system that promises forward design.
