摘要:为解决现行BIM建模设计软件不能满足当下信息化成果交付需求、市政道路BIM正向设计进展缓慢、无法很好处理机场陆侧市政道路工程等交通组织复杂场景的困境和难题。本文基于广联达数维道路BIM设计平台开展市政道路BIM正向设计研究，以广州白云国际机场三期扩建工程- 陆侧市政道路工程作为实际项目依托，对项目进行道路全构件信息化处理、BIM正向设计建模分析及工程量自动计量等相关应用，得出了数维平台在精细化建模、工程量统计及成果集成交付等方面具有较高应用价值，验证了基于数维平台的市政道路工程全过程BIM正向设计的可行性。研究项目作为市政道路专业BIM模型一体化、工程量辅助计量、施工图输出和多专业协同设计的示范应用，对于促进市政交通行业BIM正向设计水平的持续发展具有积极作用。

Abstract: In order to solve the difficulties of the current BIM modeling and design software that can not meet the current demand for the delivery of informatization results, the slow progress of the forward design of municipal road BIM, and the inability to deal with the complex traffic organization scenarios such as the airport landside municipal road project, this paper carries out the research on the forward design of municipal road BIM based on the Guanglianda digital road BIM design platform. Based on the Guangzhou Baiyun International Airport Phase Ⅲ expansion project - landside municipal road project, the project has been applied with road component informatization, BIM forward design modeling and analysis, and automatic measurement of quantities. It is concluded that the digital dimension platform has high application value in fine modeling, quantity statistics, and results integration and delivery, It verifies the feasibility of BIM forward design in the whole process of municipal road engineering based on digital dimension platform. As a demonstration application of BIM model integration, engineering quantity auxiliary measurement, construction drawing output and multi-disciplinary collaborative design in municipal road, this research project plays a positive role in promoting the sustainable development of BIM forward design level in municipal transportation industry.
