Research On The Optimization Scheme Of Breakwater Engineering Of Shijiu Port In Rizhao Based On The Analysis Of Navigational Safety

Rizhao Port is located on the South side of Shandong Peninsula, adjacent to Qingdao Port in the north and to Lianyungang in the south, a convenient estuary in the west of China's Beijing-Shanghai line and in the zone along the Eurasian Continental Bridge, having a superior location advantage and good port construction conditions. After nearly 20 years of construction and development, Rizhao Port has developed from a simple port of the energy output into an integrated fully functional port.In accordance with the overall planning of Rizhao Port, she is divided into two harbor areas, Shijiu and Lanshan. However, with the increasing of port handling capacity, existing berths'capacity have been unable to meet the growing needs of throughput, so there is an urgent need for the construction of new berths. According to the requirements of the overall planning of Rizhao Port, the construction of new berths will be south to the future along the west end container berths. The cover conditions of new berths go from bad to worse. The constructed work ship berths are directly affected by the impact of the south waves with bad operating conditions. Consequently, there is an urgent need to build a breakwater to improve the stable berthing conditions of the harbor area.Through the analysis of the wind, flow, waves and other natural conditions, as well as the density of vessels, accidents and other factors, in conjunction with the different design proposals of the breakwater, the paper builds related models, comes to the navigation conditions data of different conditions and different proposals, combines with norms to conduct contrastive analysis, and finally elects the most suitable breakwater design proposals for Shijiu area of Rizhao Port, simultaneously brings forward the optimal navigation program linked with the proposal.Chapterâ… of this article sets out the background, purpose and significance of the study, as well as the research methods and content; chapterâ…¡provides an overview of the main study (breakwater project); Chapterâ…¢analyses the ports,waterways, hydro, meteorology and other informations of the project waters; Chapterâ…£ analyzes the impact of breakwater project on the navigation environment; Chapterâ…¤analyzes the impact of the breakwater project on the navigation of the ship; Chapterâ…¥analyzes the navigable risks of the breakwater project waters; Chapterâ…¦of the paper summarizes the contents of the study and comes up with the corresponding viewpoint.In this paper, the research on the optimization program of the breakwater can objectively provide a theoretical basis and some recommendations for the guarantee of the ships' safe navigation in this waters, can optimize the navigable conditions of the breakwater project waters in Shijiu area of Rizhao Port to make the ship come in and go out safely and orderly, so that the construction of the breakwater creates a better effectiveness for Shijiu area, at the same time, it can ensure the safe navigation of the waters to maximum extent.
