摘　　要：翻坝公路与通航建筑物两类过坝方式的主导权,分别由货主和通航管理局所主导。针对货物过坝主导方的异质性,首先建立了各过坝方式的效用函数来分析主导权的转移机制。然后据此结合通航建筑物过坝原则,构建了货运量分担率多目标优化模型。最后以三峡工程为例,探讨了翻坝运输费率和船舶过坝顺序对分担率的影响,进而探讨了缓解大坝通航拥堵的决策机制。结果表明:提高翻坝公路的货运分担,可以有效改善船舶及货物的过坝运输状况;相比翻坝运输费率,降低装卸费率能更有效地提高翻坝公路货运分担水平;船舶过坝存在一个次序区间,使得水运货物经由通航建筑物过坝和经由翻坝公路过坝的效用相同。The dominant rights of the two types of dam-passing methods,such as the crossing-dam road and the navigation building,are led by the cargo owner and the navigation authority.In view of the heterogeneity of the cargo dam master,the utility function of each dam-passing method is first established to analyze the transfer mechanism of the dominant power.Then,based on the principle of passing-dam of navigation buildings,a multi-objective optimization model of freight volume sharing rate is constructed.Finally,taking the Three Gorges Project as an example,the influence of the crossing-dam transportation rate and the ship passing sequence on the sharing rate is discussed,and then the decision-making mechanism for mitigating dam navigation congestion is discussed.The results show that improving the freight sharing of the crossing-dam road can effectively improve the transportation status of the ship and cargo;compared with the crossing-dam transportation rate,and reducing the loading and unloading rate can more effectively improve the freight sharing level of the crossing-dam road.There is a sequence interval between the ship and the dam,enabling the utility of the waterborne cargo to pass the dam through the navigable building or through the crossing-dam to be the same.
