Themodel scalewas1 颐 36郾5. Duringthetest, the stabilities of thewater intake bucket andthefirst quadrate culvert andthe enclosure structurewere observed,andthe o鄄 riginal design schemewas optimized using the FL鄄NHmotion measuring system to measurethewater bucket head and quad鄄 rate culverts displacement. The wave pressures of the water intake bucket and the first quadrate culvert were measured in謖 thistest.
