[Abstract]
The method using the airlift assisted with the self oscillation pulsed jet for dredging in the Three Gorges Reservoir Region has been presented. The physical and mathematical model of airlift has been given. The feasibility of the self oscillation pulsed jet as breaker of the airlift is researched. It is theoretically and experimentally shown that the self oscillation pulsed jet not only crushes and looses mud deposit under water, but also lifts particles of solid on the clay and sand or mud bed. The oscillation cross flow caused by the self excited oscillation jet makes particles of solid enter the end of the suction pipe easily.
