Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0028] Now take the design method of anti-silting and reducing silting in the construction period of a kind of encircling port area proposed by the present invention to be applied to the Xuwei port area of Lianyungang Port as an example, and the implementation steps are as follows:
[0029] 1. Establishment of tidal current sediment mathematical model
[0030] Established water area of about 8648km 2 mathematical model, such as figure 2 shown. The calculation area is discretized with a rectangular grid, and the grid scale is gradually encrypted from the open boundary to the project area. The maximum grid scale in the model is 405m×405m. The grid scale of the project area: the tidal current model is 15m×15m, and the sediment model It is 45m×45m, which can meet the calculation accuracy requirements.
[0031] The verification of tidal cu...
