基于BIM技术的水利水电工程逆向设计

随着科学技术水平的快速发展，传统的二维设计在水利水电工程施工中的缺点逐渐突出，制约了水利水电工程管理水平的进一步提升，而 BIM 技术的发展可以实现对工程项目过程的可视化管理，使各专业之间达到整体协同，提高工程管理水平。基于此，从逆向设计的技术路线、平台配备软件及模式等 3 个方面，介绍基于 BIM 技术的水利水电各专业的逆向设计实施模式，并通过逆向构建 BIM 模型和相关专业，如建(构)筑物、管线及堤防、金属结构和电气等专业的精细化三维建筑模型，实现各专业之间信息共享，使各专业之间达到整体协同，以提高水利水电工程中各专业的设计及施工质量和效率。由此可见，基于 BIM 技术的逆向设计在水利水电工程中值得推广。

Reverse design of water conservancy and hydropower engineering based on BIM technology

With the rapid development of science and technology, the shortcomings of traditional two-dimensional design in the construction of water conservancy and hydropower projects have been increasingly prominent and restricting the advancement of water conservancy and hydropower project management. Against this backdrop, application of BIM (Building Information Modelling) technology is introduced in this article. BIM enables visualized management throughout project lifecycle to facilitate coordinated work within water conservancy and hydropower projects, and thus to improve engineering management. This article explains from technical scheme, integrated software and work pattern how to implement BIM-based reversal design in all sectors involved in a hydro-project, such as buildings, pipelines, embankments, metal structures and electrics. The high-precision 3D modelling of them allows for information sharing so as to facilitate holistic operation, and is able to enhance the quality and efficiency of hydro-power engineering. In brief, BIM-based reversal design is worth promoting in hydro- power engineering.
