摘　　要：南水北调中线京石段供水工程起于河北省石家庄,止于北京的团城湖,渠道全长307km,由于沿线冬季天气寒冷,通常都会出现结冰现象。为了做好冰期调水运行工作,确保冰期通水工作的顺利进行,输水本文利用京石段四次冰期调度运行数据,在分析各输水渠段的冰情时空分布特征的基础上,提出了冰期输水调度的经验与规律,为南水北调中线工程的冰期调度运行、冰期灾害防治和冰期灾情预报提供技术支撑。The Beijing-Shijiazhuang section of the Middle Route of South-to-North Water Diversion Project is about 307 km long,which starts from Shijiazhuang of Hebei Province and ends at Tuancheng Lake of Beijing.Due to the cold weather in winter,water along the route is usually frozen.Water diversion operation is quite different between the ice period and normal period,thus it is necessary to investigate the water diversion regulation during the ice period in order to ensure the diversion safety.Based on the four-time water diversion regulation data during the ice period in the Beijing-Shijiazhuang section,the spatial and temporal distribution characteristics of water diversion during the ice period were analyzed.The experience and regularities of water diversion were summarized,which can provide the technical support for the water diversion,ice disaster prevention,and ice disaster forecast in the Middle Route of South-to-North Water Diversion Project during the ice period.
