张家港港区位于长江下游福姜沙南水道.从巫山港到张家港一段岸线的南岸(附图),1969年建成投产。由于该港处于分汊河段的支汊上,加以南水道下游弯道受水流顶冲,河岸土质松软,在没有护岸前坍岸严重,为此关于该港的进一步扩建问题. Zhangjiagang Port is located in the lower reaches of the Yangtze River, Fukang Shanan Waterway.From the Wushan Port to Zhangjiagang coastline of the South Bank (with photos), put into operation in 1969. Due to the fact that the port is on the branch of the Fenhe River, the curve of the lower reaches of the South Water Diversion Project is hitched by the current and the soil of the river bank is soft. As a result, there is a serious collapse of the bank before the revetment. Therefore, the issue of further expansion of the port is discussed.
