大坝混凝土裂缝产生的一个重要原因是信息不畅导致措施与管理不到位,即信息获取的不及时、不准确、不真实、不系统,以及温控施工过程温差大、降温幅度大、降温速率大、温度梯度大等,这些问题最终导致混凝土裂缝的产生。为了解决上述问题,采用信息化、自动化、智能化技术手段,结合黄登工程建设,建立了个性化理想温度控制曲线模型、温度和流量预测预报模型、温控效果评价模型、开裂风险预警模型等在线实时分析模型;开发了全坝全过程仿真分析关键技术与程序,以及普适、稳定和高精度的自动化监测和控制的仪器和设备;研发各软件功能模块和子系统,并集成为一个完整的数字黄登大坝混凝土温控智能监控系统。本系统实现了海量温控及相关要素的全面、准确、及时地自动化采集,实现了海量温控信息的自动化分析、评价和预警报警以及干预措施决策支持,实现了全坝"无人工干预"理想化智能化通水冷却,在提高通水冷却施工质量的同时降低了施工差错率。应用该系统对黄登水电站大坝温控信息进行动态高效地集成管理和实时控制分析,从根本上达到混凝土温控防裂的目的,提高了黄登水电站建设质量和信息化管控水平。

Combined with the construction of Huangdeng Hydropower Station,the online real time analysis models,i.e.individual ideal temperature control curve model,temperature and flowrate prediction and forecast model,temperature control effect evaluation model,cracking risk early-warning model,etc.are established by the technical means of informatization,automation and intelligentization,and then the key techniques for the entire dam and whole process simulative analysis and the relevant programs as well as the universal,stable and highly-accurate instrument and equipment for the automatic monitoring and control are developed,while all the software function modules and sub-systems are developed as well,which are integrated into a complete digitalized intelligent concrete temperature control system for Huangdeng Dam.This system realizes the comprehensive,accurate and timely automatic collection of massive temperature control information and relevant key factors,thus realizes the automatic analysis,evaluation and early-warning of massive temperature control information and the decision-making support for the relevant interventive measures,and then the idealized-intelligent no manual intervention water cooling of the entire dam is realized as well,which does not only enhance the construction quality with water cooling,but also decrease the error rate of the construction.This system performs the dynamic and highly-efficient integrated manage and the real-time control analysis of the temperature control information for Huangdeng Dam,thus fundamentally gets the target of temperature control and crack prevention,and then improves the construction quality and informatized management and control level of Huangdeng Hydropower Station.
