【摘要】：近年来,随着江苏沿海经济的快速发展,大丰港货物吞吐量和到港船舶大幅增加,为满足港口生产运营的需求,拟对一号锚地进行扩容施工。扩容工程改变了港口原有通航环境,产生潜在安全隐患,为保证通航安全,保护水域环境,对大丰港锚地扩容工程进行通航安全评价。在对影响通航安全的因素的研究工作中,主要从工程状况、自然环境、港口环境、交通环境、港口管理等方面收集整理资料并进行分析。运用层次分析法对各影响因素进行筛选,建立起了由气象、水文、地形地貌、助航设施、交通事故分布、碍航物、船舶交通服务、海上救助、港口应变部署等12个指标组成的安全评价指标体系。然后运用层次分析法建立递阶层次结构模型,通过两两比较,根据走访专家并填写专家调查表的结果构建出判断矩阵,通过权重计算以及一致性检验确定出各安全评价指标的权重。在此基础上运用模糊综合评价法建立评价指标体系,确定了低风险、正常风险、较高风险、高风险、极高风险的评价指标评价集,确立评价指标权重集,确定单因素模糊评价矩阵,最后进行模糊综合评价。评价结果显示该工程对所涉水域船舶通航存在较高风险,根据评价结果给出了提高通航安全的建议,采取施工船舶管理、选择施工时机、优化交通流、规划进出锚地航行带等几个方面的措施,可以有效提高工程所涉水域通航安全。该研究为工程建设单位提供了项目安全管理参考,同时也为有关部门对本工程审批和日常安全监督管理提供依据。
[Abstract]:In recent years, with the rapid development of Jiangsu coastal economy, the cargo throughput and arrival ships of Dafeng Port have greatly increased. In order to meet the needs of port production and operation, the construction of Anchor No. 1 is to be carried out. In order to ensure navigation safety and protect water environment, the navigation safety evaluation of Dafeng Port Anchorage expansion project was carried out in order to ensure navigation safety and protect the environment of water area, which changed the original navigation environment of Dafeng Port. In the research work of factors affecting navigation safety, the data are collected and analyzed mainly from the aspects of engineering condition, natural environment, port environment, traffic environment, port management and so on. The analytic hierarchy process (AHP) was used to screen the influencing factors and set up meteorological, hydrological, topographic, navigational facilities, distribution of traffic accidents, obstruction of navigation objects, ship traffic services, and rescue at sea. The safety evaluation index system is composed of 12 indexes, such as port contingency deployment and so on. Then the hierarchical structure model is established by analytic hierarchy process (AHP), and the judgment matrix is constructed according to the results of visiting experts and filling in the expert questionnaire through pairwise comparison. The weight of each safety evaluation index is determined by weight calculation and consistency check. On this basis, the fuzzy comprehensive evaluation method is used to establish the evaluation index system, and the evaluation index set of low risk, normal risk, high risk and extremely high risk is determined, and the weight set of evaluation index is established. The single factor fuzzy evaluation matrix is determined and the fuzzy comprehensive evaluation is carried out at last. The evaluation results show that the project has a high risk to the navigation of ships in the waters involved. According to the evaluation results, suggestions to improve navigation safety are put forward, construction ship management is adopted, construction time is chosen, and traffic flow is optimized. The safety of navigation in and out of the waters involved in the project can be effectively improved by planning the navigation zone in and out of the Anchorage. The study provides a reference for the project safety management of the engineering construction unit, and also provides the basis for the relevant departments to examine and approve the project and to supervise and manage the safety of the project on a day-to-day basis.
