面向桩基成孔施工质量管控的数字孪生体系构建

Establishment of a Digital Twin Framework for Quality Management of Pile Foundation Drilling

摘要: 桩基工程作为隐蔽工程，其施工过程容易产生孔位和垂直度偏差，钻孔深度和入岩深度不足等安全隐患，采用信息化技术实现其施工质量管控至关重要。现阶段面向桩基成孔施工质量管控的数字孪生理论体系缺乏是制约桩基工程信息化发展的瓶颈之一，除了个别碎片化的应用探索外，鲜有可供参考的系统性案例。本文从桩基成孔施工的数字孪生基本概念出发，系统阐述了其框架构成，构建了一个由数字孪生技术驱动的桩基成孔施工质量管控框架体系。以泥浆护壁钻孔桩为例，提出了其成孔施工质量管控的指标与预警标准，为数字孪生技术在桩基成孔施工质量管控中的应用提供参考。

Abstract: As a concealed engineering project, pile foundation construction is prone to hole position deviations, verticality deviations, insufficient drilling depth, and rock penetration depth, posing safety hazards. Utilizing information technology is crucial for controlling the construction quality. Currently, the lack of a digital twin theoretical system for controlling the quality of pile foundation drilling constrains the development of information technology in pile foundation engineering. Apart from sporadic fragmented application explorations, there are few systematic cases available for reference. This article starts from the basic concept of digital twin technology in pile foundation drilling construction, systematically elaborates on its framework composition, and constructs a pile foundation drilling quality control framework system driven by digital twin technology. Taking mud-covered wall drilling piles as an example, it proposes indicators and warning standards for quality control during drilling, providing a reference for the application of digital twin technology in quality control of pile foundation drilling construction.
