白鹤滩特高拱坝智能建造技术与应用实践

Intelligent construction methods for the Baihetan super high arch dam

在大数据和人工智能背景下,工程建设项目与现代信息技术逐步融合,以溪洛渡水电站为代表开创了高拱坝智能化建设的先河,随着信息技术、传感与数据处理技术的升级和迭代,需同步升级与纵深发展。依托白鹤滩300 m级特高拱坝建设实践,该文提出智能建造筑坝理念,以全面感知、真实分析、实时控制的闭环控制为理论基础,构建面向关键施工工艺和业务流程的智能建造技术体系及相关基础部署条件,研发并形成浇筑一条龙监控、平仓振捣监控、智能通水、智能喷雾、智能灌浆等核心智能筑坝成套新技术,详细阐述其闭环智能控制流程及功能。实践结果表明:项目构建形成了"一个中心、两个支撑、三个支柱"的产、学、研、用深度融合项目管理新模式,为工程优质、高效、安全建设提供管理和技术支撑,带来了较大的经济与管理效益,可为类似工程智能建造提供参考。

Construction projects are making use of modern information technology methods such as big data and artificial intelligence to improve project construction.The Xiluodu Hydropower Project is a pioneer application of intelligent construction methods for high arch dams.However,the rapid advances in information,sensing and data processing methods require further development of intelligent dam construction methods.Intelligent dam construction methods are introduced here as applied to the Baihetan Hydropower Project,a 300-meter ultra-high arch dam,with extensive monitoring measurements,real analyses,intelligent decision making and feedback control.This paper describes the intelligent construction system and its implementation with a focus on key construction processes and business processes including whole-process concrete placement monitoring,concrete leveling and vibrating monitoring,intelligent water-cooling,intelligent spraying and intelligent grouting.This paper then further describes the close-loop control of these intelligent methods and their functions.
