The Development of Offshore Artificial Island Construction and Application of Key Hydrodynamic Technologies in China ——Take Haihua Island Project as an Example

In recent years, with the development of China’s coastal waters and coastal urban space expansion needs, the construction of artificial islands on the sea has achieved rapid development. In order to allow it to further promote the development of Marine economy in our country, relieve the contradictions of land and environmental pressure and maintain the Marine ownership plays an important role in our country, research from the review summarizes the development of China offshore artificial island and the technical characteristics of typical artificial island has been built and under construction engineering examples, the paper introduces the construction and offshore artificial island development present situation, and sums up the construction of artificial islands facing the core issues. At the same time, based on the analysis on the status at present domestic offshore artificial island, points out the key technology of the construction of the island, and in the sea flower island project carried out by the series water power project as an example, a detailed discussion on wave flow elements, the seabed sediment, as well as the influence on surrounding channel water exchange, and the three dimensional seepage flow, etc. The research achievements of the project. The research points out that the future construction of artificial islands should return to rationality and science and pay more attention to the integration of natural ecology and environment.
