Abstract

In this paper, the two-dimensional water mathematical model of the Pearl River Estuary is established. Based on the verification of the hydrological data, the tidal current characteristics of the prefabricated immersed pipe pouring area and the floating channel are simulated, and the characteristics of the velocity fluctuation of the characteristic point are analyzed. The simulation results show that after the project is implemented, the tidal current velocity in the waters of the Longxue harbor basin is generally weak. The flow velocity of the basin in the Nansha Phase IV is relatively small, and the circulation in the water area of the mouth is weak, which provides favorable conditions for the anchorage of the platform; The maximum transverse flow is less than 1 mile/h, and the average value of the maximum transverse flow during the mid-tidal period is about 0.4 m/s; the maximum longitudinal outflow is now the AC and DE, and the maximum longitudinal flow during the neap tide period does not exceed 2 mile/h, and the navigation flow during the neap tide period. Conditions provide technical support for the location of the immersed pipe pouring area and the selection of the floating channel.
