[Objective] The flume simulation research on wave prevention and sand stabilization counter measures for coral sandy coastlines were studied in order to provide a theoretical basis for the project to protect coastlines against wave erosion along the Dengloujiao shoreline, located in the Xuwen National Coral Reef Nature Reserve on the Leizhou Peninsula, and to provide technical support for similar coastal areas. [Methods] The coastal erosion protection effect of san-dbag barrier measures was determined for the Dengloujiao coastline using a flume experiment simulation method. [Results] ① The composite effect of the overall structure of the diamond-shaped sand-bag barrier had a significant impact on the stability of the sand barrier. Two groups of sand barriers with a diameter of 5 cm or above was able to achieve self-stability. Calculated according to the gravity similarity criterion, this was equivalent to 50 cm diameter of the prototype; ② The sand-bag barrier achieved sediment fixation by increasing the roug
