The Research On The Reasonable Planning And Design Of Port Fairway

Ships' large scale, harbor scale magnification, have made the original traffic tension on the waters of the port fairway to bear greater pressure, which forced the port fairway waters need to re-planning, promotion, to ease transportation pressure at the present and to meet requirement of future development.For the enhancement harbor waters ships' navigation security, the paper from the path of rational planning point of view, has made the summary in view of the current classics' some fairway planning, and has made the improvement to the fairway water depth's planning, in the classics planning, joins the water depth measuring error parameter, and makes the analysis about the rationality of this parameter.The classical route planning plan mainly are depend on the experience summarizes, its scientific nature and rationality lack the theory safeguard, therefore, this paper utilizes the fuzzy comprehensive evaluation method, through makes the evaluation after the fairway plan's navigation security, by this judgment fairway planning rationality. The evaluation is different from the risk assessment of ship in the waters navigable environment, the essential factors considered are mainly the rigid target, therefore, the human factor, the traffic flow and other man-made factors that can control are removed outside the comprehensive evaluation system. To establish the index system about the fairway navigation security after planning, aiming at some indexes the paper designates new evaluation standards approved by experts. In the specific implementation of the evaluation process, in view of the square-root method to determine weight's formula, the paper makes the confirmation to the largest eigenvalue using the MATLAB software, and guarantees that the approximate eigenvalue is closer the actual value. The Qingdao port's scale expands gradually, the inward and outward ships' large, in Jiaozhou Bay, the fairway planning and promotion are imperative, the paper put forward the planning proposal to the Qingdao port's fairway planning, at the end, adoption of comprehensive security assessment model shows that the recommendations of scientific and reasonable. The conclusion is that the fairway planning method in this paper is basic feasibility, and has certain reference to the port waters' fairway planning.
