Study on scour around a structure on silt-sandy seabed by extension method of series models;

Regarding natural sand of the spot as model sand,using series model,and under the interaction of irregular wave and tidal current,a systematic test on scouring around pile of land-island approach bridge of Jiangsu LNG Receiving Station is carried out.

Relying on the anti-scour wall of centre bar in Jiayu-Yanziwo channel,and according to the results of series model test,we carry out a research on the flow property and scouring characteristics of centre bar head before and after the anti-scour wall engineering,and propose optimized anti-scour wall design and conservation programs.
