摘要

As the first 500kV submarine cable project in China, the Southern Power Grid and Hainan networking project plays an important role in the development history of China's power industry. The 500kV submarine cable of Fuxujia line passes through Qiongzhou strait from north to south, with complex seabed topography and dense distribution of sand waves. Under the condition of strong hydrodynamics, the stability of the bottom of Qiongzhou strait is poor and scour phenomenon is easy to occur. In order to ensure the long-term safe operation of the cable, the landform and topography of submarine cable route should be inspected regularly. Based on the changes of topography of submarine cable routing, this paper analyzed the sediment movement in this area, and studied the stability of submarine cable routing area and the movement trend of sand slope, and provided scientific basis for the protection of submarine cable.
