Problems solved by technology
For example, the direction of the channel should be as parallel as possible to the main direction of the water flow to reduce the cross flow of the ship when navigating in the channel to avoid the risk of navigation; the velocity and direction of the water flow in the berthing waters of the port will directly affect the safety of the ship when berthing; in addition, the harbor basin The water flow in the channel and the water flow will also affect the sedimentation in the water body, and the sea area with excessive sedimentation will increase the dredging and maintenance costs during the port operation period

Embodiment 1
[0089] The present invention takes the proposed port area (Dianbai County, Maoming City, that is, near the coast of western Guangdong) located in the Maoming sea area in western Guangdong as an example to further illustrate the port construction method of the present invention considering residual currents. Among them, in western Guangdong, the remaining current is approximately equal to the coastal current in western Guangdong.
[0090] 1. Range selection of the mathematical model of the port area
[0091] Firstly, determine the scope of the mathematical model of the port area. In order to avoid the input error of the open boundary of the open sea and simulate the impact of the proposed port channel project on the surrounding engineering sea area after the implementation, the model range should be as large as possible.
[0092] In this embodiment, the east border is to Hailing Island, and the west border is to Zhanjiang. Special attention should be paid to the fact that the...

The invention discloses a port construction method considering residual currents: step 1, determining the range of the mathematical model of the port area and performing grid division on the mathematical model of the port area; step 2, analyzing the characteristics of residual currents in the port area, and obtaining each measured Step 3, determine the open boundary of the tidal level of the mathematical model of the port area; Step 4, determine the boundary of the residual current level of the mathematical model of the port area; Step 5, superimpose the boundary of the residual current level on the open boundary of the tidal level , to obtain the final open boundary of the mathematical model of the port area; step 6, confirm the final grid division according to the port planning, perform simulation calculations according to the final open boundary and final grid division, and carry out port design according to the simulated calculation results. The invention fully considers the impact of residual currents during port construction, and the water flow in the port area simulates real water flow, and the simulation results are accurate and reliable, providing accurate guidance for port construction.
Description
technical field [0001] The invention relates to port construction, in particular to a port construction method considering residual current. Background technique [0002] The sea area of Western Guangdong is surrounded by Guangdong Province, Leizhou Peninsula and Hainan Island to the north and west respectively ( figure 1 ), the seabed topography slopes sharply from west and north to southeast. There are many rivers along the coast that flow into the sea, among which the Pearl River has the largest runoff, and its annual average runoff totals 336 billion m 3 . [0003] Early people thought qualitatively of the coastal current in western Guangdong that it changes with the seasons, flowing westward in winter and eastward in summer, such as figure 2 and image 3 shown. In the past 20 years, with the increase of observation and research results, people have a new understanding of the coastal current in western Guangdong, that is, there is a coastal current flowing to the...
