【摘要】 鉴于数学模型在解决水沙运动及河床冲淤变化三维性较强的局部工程问题时存在一定的局限,以及物理模型在模拟长河段时受时间变态影响较为严重的问题,提出综合物理模型和数学模型优点的长河段复合模型。综述国内外复合模型的发展情况、优缺点及发展趋势,结合物理模型和数学模型在航道整治工程中的应用,提出航道整治工程中长河段复合模型研究思路与方法。更多还原

【Abstract】 Since there are some limitations when we solve some engineering problems by the mathematical model and physica I mode I,we propose a long river reach hybrid model synthesizing the advantages of the physical model and mathematical model,summarize the development situation and the advantages and disadvantages of the model at home and abroad. Combining with the applications of the physical model and mathematical model in waterway regulation engineering,we put forward the research idea and method of long river reach hybrid model in the waterway regulation engineering.更多还原
