摘要:
以长江口澄通河段为研究区,利用2006年和2012年实测水下地形数据,建立河道数字高程模型,结合长江口来水来沙现状和河段特征,分析了在三峡建坝后澄通河段水下地形的冲淤变化以及河床演变趋势,研究了澄通河段典型断面的变化情况。结果表明,随着以三峡水库为代表的长江上游梯级水库群的建成蓄水,长江下游来水量变化不大,但来沙量显著降低,澄通河段在2006年至2012年间河道呈现冲刷状态,福中水道和福北水道分别发生了冲刷和淤积,浏海沙水道的深槽位置发生摆动,右侧河道变宽,天生港附近的通州沙东水道右侧深槽处于刷深状态,而狼山沙东水道河槽向左偏移明显。
Abstract:
Taking Chengtong reach of the Yangtze River Estuary as a research area, using the measured underwater topographic data in 2006 and 2012, the digital elevation model of the river channel was established. Based on the current situation of inflow and sediment in the Yangtze River Estuary and the characteristics of the river section, the scouring and silting changes of the underwater topography and the evolution of the river bed in the Chengtong reach after the construction of the Three Gorges dam were analyzed, and the changes of typical sections in the Chengtong reach were studied. The results showed that, with the completion and storage of cascade reservoirs in the upper reaches of the Yangtze River represented by the Three Gorges Reservoir, the inflow of the lower reaches of the Yangtze River had little change, but the amount of sediment was significantly reduced. The river channel of the Chengtong reach was scoured from 2006 to 2012, and the Fuzhong and Fubei waterways were scoured and silted respectively. The position of the deep channel of the Liuhaisha waterway was oscillating, and the right channel was widened. The right deep channel of the Tongzhou Shadong waterway near the Tianshenggang was in the state of brushing depth, while the channel of the Langshan Shadong waterway was obviously shifted to the left.
