【摘要】：内河航道建设中在分汊河段面临汊道选择问题,尤其是大型内河航道建设因投资巨大且对河段航道格局有长期影响,选汊涉及的因素繁多且无法直接比较。以长江南京以下12.5 m深水航道福姜沙河段的选汊问题为例,在对不同选汊方案的港口适应性、通航组织风险、航行干扰、施工期运营期风险、航道服务水平、锚地便利性、投资及航道维护等方面分析的基础上,采用主客观综合评价法(CRITIC),建立多目标决策评价模型。根据模型计算结果对选汊方案优劣排序,并进行稳定性检验,得出福中+福北方案为最优选汊方案。
[Abstract]:In the construction of inland waterway, branching channel is faced with the problem of selection of branching channel, especially because of huge investment and long-term influence on channel pattern of large inland waterway, there are many factors involved in the selection of branching channel and it can not be directly compared. Taking the selection of branches in the Fujiangsha River section of the deep water channel of the Yangtze River below 12.5 m below Nanjing as an example, the port adaptability, navigational organization risk, navigational interference, operational risk during construction period, channel service level and convenience of Anchorage are studied. Based on the analysis of investment and waterway maintenance, a multi-objective decision evaluation model is established by using subjective and objective comprehensive evaluation method. According to the results of model calculation, the selection scheme is ranked, and the stability test is carried out. It is concluded that the Fuzhong Fubei scheme is the best one.
