Abstract

The temperature control and crack prevention of the high dam is with very much difficulties. One important reason is that the unsmooth information causes improper measures and management, that is "four don't" for obtaining the information- not timely, not accurate, not true, not systematic; furthermore, "four top" problems during the temperature control construction process can't be controlled easily, that is: large temperature difference, large scale of drop in temperature, high rate of temperature fall, large temperature gradient, which could finally cause the generation of distress in concrete. In order to solve "four don't" to control "four tops", take informationized, automatic and intelligent technical methods, establish individual ideal temperature control curve model, temperature and flow prediction and forecasting model, temperature control effectiveness evaluation model, crack risk alarm model and other online real-time analysis models, develops key technology and processes for simulative analysis of the whole process of the whole dam, develops pervasive, stable and highly precise automatic monitoring and controlling instrument and equipment, researches and develops all software function models and sub-systems, integrates a complete digital concrete temperature control intelligent monitoring system for Huangdeng Dam, realizes comprehensive, accurate and timely automatic collection of large quantity of temperature control information and relevant key factors, realizes automatic analysis, evaluation and warning and alarm as well as support of intervening measure decision for large quantity of temperature control information, realizes intelligent water cooling of the whole dam under the "non-manual intervention" ideal conditions, and improves the water cooling construction quality while reducing the construction error rate. The system dynamically and high-efficiently manages, real-timely controls and analyzes the temperature control information of Huangdeng Hydropower Dam with many characters, such as real-time, continuity, automation and intelligentization, etc., it effectively manages all links during the temperature control process of the dam, realizes online real-time monitoring and feedback control of construction, which is able to effectively solve "four don't" and control "four tops", basically realizes the temperature control and crack prevention of concrete, and improves construction quality and informatization control level of Huangdeng Hydropower Station.
