Research on key technology of sponge city life cycle management and control based on BIM

针对传统二维措施无法有效应对海绵城市全生命周期跟踪统筹、水文涝情精准决策等管控问题,基于海绵城市规划建设运维管控特点分析,探索提出基于BIM技术的海绵城市规划建设运维管控关键技术,包括技术框架设计、海绵城市BIM创建方法和海绵城市BIM管控平台构建等三方面。首先从BIM创建、数据库、应用管控平台三方面提出基于BIM技术的海绵城市规划建设运维管控技术框架,形成顶层设计;其次,提出海绵城市三维可视化模型的创建、分类、集成方法,并以此模型成果为载体构建海绵城市BIM管控平台,通过提取、关联、集成海绵城市全生命周期数据,实现从源头-过程-末端全过程三维立体可视化统筹管理海绵城市建设与运维。

In order to solve the problem that the traditional two-dimensional measures will be unable to respond effectively to sponge city life cycle planning and precise decision-making of hydrology, based on the analysis of the characteristics of sponge city life cycle, this paper explores and puts forward the key technology of sponge city life cycle management and control based on BIM. The key technology includes three aspects: technical framework design, sponge BIM creation method and sponge BIM management and control platform construction. Firstly, the technical framework of sponge city life cycle management and control based on BIM technology is put forward from three aspects: BIM creation, database and application platform. Secondly, the method of creating, classifying and integrating the three-dimensional visualization model of sponge city is put forward. Finally, the management and control platform of sponge city life cycle is constructed with the model achievement as the carrier, through extraction, association, integration of sponge city life cycle data. This platform is helpful to realize the three-dimensional visualization management of sponge city from the source-process-end process.
