Abstract: In order to ensure the navigation safety of wharfs near the bridge, the factors affecting the wharf capacity loss were analyzed, and the indexes of wharf capacity loss affected by the bridge were determined. A model of wharf capacity loss based on grey fuzzy was proposed. According to the membership degree of grey correlation degree, the weight of each factor was distributed and calculated by AHP. Taking Yongzhou Bridge as an example, the feasibility of the method was verified, and 5 effective index factors were selected to complete the quantitative analysis of wharf capacity loss. The proposed model is helpful to strengthen the safety planning and management of wharf and ensure the navigation safety of ships in the bridge area, which provides a scientific reference for the route selection of the bridge location.

Key words: port engineering, wharf capacity loss, grey fuzzy, grey correlation degree, analytic hierarchy process, loss rate

摘要: 为保障大桥附近的码头通航安全,分析影响码头能力损失的因素,确定受大桥影响的码头能力损失指标,提出了基于灰色模糊的码头能力损失模型。根据灰色关联度的隶属度求解,用层次分析法分配计算各个因素权重,以甬舟大桥为例,验证了方法的可行性,并选取5个有效的指标因素,完成了对码头能力损失的定量分析。研究有利于加强码头安全规划管理、保障桥区船舶通航安全,为桥位线的选线提供了科学参考依据。
