Harbor construction method considering residual flow

Abstract

The invention discloses a harbor construction method considering residual flow. The method comprises the following steps: 1, determining a harbor area mathematical model range and carrying out mesh generation on a harbor area mathematical model; 2, analyzing the harbor district residual flow characteristics to obtain the residual flow velocity and the residual flow direction of each measuring point; 3, determining a tide level opening boundary of the harbor area mathematical model; 4, determining a residual water level boundary of the harbor area mathematical model; 5, superposing a residual water level boundary on the tide level open boundary to obtain a final open boundary of the harbor area mathematical model; and 6, determining final mesh generation according to port planning, performing analog computation according to the final open boundary and the final mesh generation, and performing port design according to an analog computation result. The residual flow influence is fully considered during port construction, the port area water flow simulates the real water flow, the simulation result is accurate and reliable, and accurate guidance is provided 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...

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
