摘要:

智能化是桥梁建设的重要方向,数字孪生是实现桥梁智能建造的有效途径。数字孪生将现实环境中桥梁的结构、状态和行为等映射到虚拟环境,为透彻理解和精准控制桥梁建造过程提供新手段。本文首先分析了桥梁及其环境高精度数字孪生与桥梁智能建造背景及发展趋势,然后提出了桥梁建造全过程数字孪生构建方法,探讨了空天地一体化监测数据关联融合、数字孪生场景智能构建与增强可视化、过程动态仿真与智能预测等关键技术,最后以复杂艰险山区大型桥梁建造为例开展案例应用分析,本文方法可望为复杂环境大型桥梁工程智能建造提供有效的理论指导和关键技术支撑。

An Intelligent Bridge Construction Method Driven by Digital Twin
Abstract:

Intelligence is an important direction of bridge construction, while the digital twin is an effective way to realize intelligent bridge construction. Digital twin maps the structure, state and behavior of bridges in real environment into a virtual environment, which provides a new means to thoroughly understand and precisely control the bridge construction process. First, this paper analyzed the background and development trend of high-precision digital twin and intelligent construction of bridges and their environment. Then a digital twin construction method for whole process of bridge construction was put forward, and several key technologies such as space-air-ground integrated monitoring data association and fusion, digital twin scene intelligent construction and enhanced visualization, process dynamic simulation and intelligent prediction was discussed. Finally, it took the construction of large bridges in complex and dangerous mountainous areas as an experiment case to carry out application analysis. The proposed method is expected to provide effective theoretical guidance and key technical support for intelligent construction of large bridge engineering in complex environment.
