| 摘 要： | Using an irregularly oscillating tray and flume,a series of experiments are completed to evaluate bed-load sediment transport rate under irregular wave-current coexistent fild.Testing conditions include three interaction angles 0°,45°,90° and two kinds of median sizes (0.38 and 1.10 mm).The results of transport rate show that the net sediment transport rate can be expressed approximately as the function of the maximum bottom shear stress of waves,mean shear stress of current and the grain size.
