The large number of anchorage，complex water topography and various types of ship berthing in the Three Gorges Dam area have brought difficulties to the popularization and application of shore power technology.From the point of view of infrastructure，this paper conducts research and analysis on the anchorage and ships waiting for lock in the Three Gorges Dam area，combining with the four common ship berthing modes in the three Gorges Dam area：barge，vertical pier，Ding berthing and anchoring.The mode and layout of shore power access to anchorage in the Three Gorges Dam area are studied，and a feasible differential anchorage access scheme is put forward，providing ideas and technical support for anchorage shore power construction.It can not only solve the problem of ship pollution in the Three Gorges Reservoir area，but also is of great significance for the construction of water green service area and promoting the development of green shipping in the Yangtze River Economic Belt.
