混凝土高坝开裂是普遍存在的现象，国内外许多混凝土坝都因施工裂缝而被迫停工处理。混凝土高坝的浇筑施工过程受到自然环境、结构形式、温控、资源等多种因素的影响，如何综合考虑这些影响因素制定切实可行的大坝浇筑施工计划，并在施工过程中加强对混凝土温度和应力的实时监控和科学管理十分必要。混凝土高坝施工过程决策支持系统的研究开发，能够为水电大坝的建设和安全提供先进的管理路径，具有巨大的潜在效益。以立洲水电站工程为依托，研发了高RCC拱坝施工期温控决策支持平台，实现了碾压参数、温控信息、监测数据和仿真成果等数据信息的高效管理，大坝温控防裂效果和趋势的实时监控和预测预警，以及专家远程会商决策支持，对促进高RCC拱坝施工温控决策支持科学化水平和确保施工质量具有重要意义。

Cracking in high concrete dam is a common problem. Many concrete dams in China and abroad are forced to shut down due to cracks in construction. The process of pouring high concrete dam is affected by natural environment, structure, temperature control, resources and other factors. It is necessary to develop a practical plan of dam construction by considering these factors. Real time monitoring and scientific management of concrete temperature and stress during construction are also requisite. Research and development of decision support system for concrete dam construction can provide advanced management approach for the construction and safety of hydroelectric dams, and potential benefits will be huge. With the project of Lizhou hydropower station as research background, a temperature control decision support platform for high RCC arch dam is developed. Through this platform, data information such as rolling parameters, temperature control information, monitoring data and simulation results are efficiently managed. Moreover, the effect and trend of temperature control are realtime monitored and predicted, earlywarning is accomplished and decisionsupport from experts remote consultation is provided. These results are of important significance for promoting the scientific level of construction temperature control decision support for high RCC arch dam and ensuring the construction quality.
