摘要
南水北调中线工程全长1400多km,大型建筑物数量多,沿线没有一座在线调节水库,沿线气象、水文条件复杂,控制难度大,冰期输水问题尤其突出。针对南水北调中线工程的特点,采用数值模拟和试验研究相结合的方法,对中线工程的冰期输水能力和冰窖防治技术、输水模式、极端冰窖条件和防冰措施进行了研究。
The Middle Route Scheme of South-North Water Diversion Project （SNWDP） has a total length of more than 1 400 km with many large structures. Along the water diversion route, there is no regulating reservoir with complex meteorological and hydrological conditions and difficulties of regulation, especially water transfer in ice condition. In light of features of the Middle Route Scheme, digital simulation and experiment are used in combination, in order to study the capacity of water transfer in ice period and prevention of ice pit, water diversion model and extreme condition of ice pit and ice prevention measures.
