摘要：The artificial influence on dredging volume in the Yangtze Estuary Deep-water Channel is significant and complicated. By studying the relationship between daily average dredging volume and daily average residual shallow point volume, the evaluating standard and correcting method of the artificial influence on dredging volume is successfully put forward, and the key technical gap is filled. The corrected results show that: 1) The artificial influence measures are the effective ways to adjust dredging volume, and the dredging volume per year is gradually stabilized in a region with a relatively low volume and a significantly reduced range.2)The channel quality is different each year, the dredging volume of the channel is reduced by the artificial influence but the channel quality is also reduced.3) Since the Yangtze estuary deep water channel was opened, the decline trend of the annual silting intensity in the Nangang-yuanyuansha channel has been significant, but the tendency variation of the annual silting intensity in the North Channel, as the main object of research and improvement on sedimentation reduction, is not declining, which is actually a little bit increasing.
