| Abstract: | According to research domestic and overseas,movable-bed physical model of pile group local scouring under tidal current was established.Tests on the model were conducted more than seventy times.Local scouring around the pile foundation with different hydrological conditions,engineering geological conditions was observed.The formation and mechanism of local scouring under tidal current were studied,and relation of tidal reciprocating flow and one-way steady flow was analysized.The calculation method of local scouring depth wide tidal flow was obtained by test data analysis. |
