摘要
寒冷地区河流冬季常产生凌洪灾害 ,因此河冰问题早在 18世纪就引起了各国学者的重视 ,研究的途径大致可分为 3个方面 :原型观测 ,即通过对特定天然河段的研究 ,了解河冰运动的规律 ,据以解决生产实际问题 ;数学模型 ,运用相应的数学、物理手段 ,借助于计算机 ,从理论上探询解决问题的方法 ;进行室内试验研究。但是 ,至今尚未形成理论上的一般方程 ,依据多相流理论 ,探讨并建立了冰、水。
Ice flood disaster often occurs in winter of cold areas, the river ice problem has been studied since the eighteenth century, and there are roughly three approaches:through observing the prototype and studying natural river reaches in specific situations to know the law of motion of river ice and solve problems in practice; through utilizing mathematical and physical methods and with the help of computers to establish mathematical models so as to find the ways of solving the problem;and through making the experimental study. However,the general equations have not been formulated so far. In this paper,based on the multiphase fluid theory,the basic equations about the movement of ice,water and sand are studied and formulated,including the continuity equation,the momentum equation,and the energy conservation equation.
