| Navigation security refers to traffic order on water,navigation,berthing and operation security.There are many factors affecting the security of navigation.The influence of natural factors on navigation security is determined by its natural attributes.To control the influence of these factors on navigation security is mainly to control its basic laws and attributes,prevent,control and make use of them as soon as possible.The impact of human factors on navigation security is related to human behavior,which is mainly reduced by scientific management and control of personnel and human operation.Natural factors mainly include natural environment(meteorology,hydrology,waterway and geology),port environment(facilities,waterway and anchorage),and human factors mainly include traffic environment and security measures.The research on navigation security impact is an important working stage that must be carried out in the early stage of construction of water-related projects(wharf,bridge,ship lock,tunnel,artificial island,beach belt,anchorage,etc.).It is an important measure to reduce the impact on navigation security caused by the construction of water-related projects and a necessary condition for the approval and approval of water-related projects.The study on the influence of navigation security can avoid the influence of the construction of wharf engineering on the navigation of ships in the past to the greatest extent,so as to guarantee navigation security,protect navigation resources,maintain navigation order and promote the development of water transport economy.Taking Tiancheng group building for wharf engineering case in addition to the natural environment,ports,transportation environment,safeguards and other traditional navigation security study,also according to the characteristics of the wharf engineering construction increased the port location,main dimensions,port of ship loading,the study of general layout,etc.According to the results of the study,to extract the influence Tiancheng group building navigation security of wharf engineering major risk factors,the creative use of fuzzy comprehensive evaluation method based on analytic hierarchy process(AHP)to Tiancheng group building for wharf engineering navigation security risk evaluation,and according to the evaluation results put forward the concrete risk control measures and Suggestions.This paper is expected to provide effective help for the construction of Tiancheng group’s new wharf project,provides a new method and idea for the research of water-involved engineering in navigation safety field... |
