【Abstract】 The number of tidal gate in the coastal waters of our country is large and the siltation is serious under the tidal gate,and it is imminent to prevent siltation and reduce siltation. The natural causes and engineering reasons of the siltation under the tide gate are introduced. The measures of anti-silting and siltation reduction for the treatment of siltation under the tidal gate are summarized. It is proposed that the determination of the time of hydraulic scour and the selection of mechanical dredging sites should be studied in the future,and we need to strengthen the research simulation of changes in water and sand erosion and siltation before sluice construction.更多还原
