摘要
根据水动力学、热力学、河冰水力学及固体力学等基本理论,针对吉林省伊丹河输水河段具体特征,建立了伊丹河的河冰数值模型,并应用1958—1988共30年的水文、气象资料对该输水河段进行了数值模拟及分析。结果表明,伊丹河输水河段冰期封冻形式为平封,可形成稳定冰盖从而实现冰期冰盖下输水,且满足冰期正常输水的要求。
Based upon the theory of hydrodynamics,river mechanics,thermodynamics,river-ice hydraulics and mechanics of solids etc.,a mathematic model of the river-ice processes for the Yidan reach is constructed. 30-year long-term series comprehensive field observation data,including geomorphy,meteorology,hydrology,thermo-dynamics and ice regime,are used to simulate the water transfer process of the Yidan River during freezing period. The results show that steady ice cover can be formed by juxtaposition on the Yidan River,which achieves the goal of water transfer beneath the ice cover. In addition,the design discharge of the Yidan River water transfer project can be guaranteed during freezing period.
