摘　　要：数字监控是混凝土坝工程质量控制新的理念。基于这一思想,研发了碾压混凝土坝数字监控系统。该系统可实现对大坝开始施工直至服役结束整个生命过程的工作性态的监控,从过程中最大限度地杜绝裂缝的产生,该系统在鲁地拉碾压混凝土重力坝中得以实施,实践表明,该系统可有效指导温控施工的全过程,成功实现了温度信息的自动获取、温控资料的数字集成和自动分析、分析成果的多方共享、预警信息的自动发布以及温控档案的备份查询等。Digital monitoring is a new concept for the quality control of concrete dam. Based on this concept, a digital monitoring system for RCC dam is developed. This system can realize the monitoring of the working behaviors of the dam through its entire life course from the beginning of construction to the end of service, and then prevent cracking from the dam body through the whole process as maximized as possible; which has been applied to Ludila RCC Gravity Dam. The engineering practice shows that this system can effectively guide the whole construction process, and then successfully realize the automatic acquisition of the tempera- ture information, the digital integration and analysis of the temperature control data, the multi-party sharing of the analysis result, the automatic transmission of the early warning information, the enquiry of the backup file of temperature control data, etc.
