长江中下游港口建设的特点除水位差大(8～15米),硬卧层埋藏较深外,从航道方面来讲,主要是担负国内城乡物资交流,在通用港口中船型不一,货种繁杂,大宗货物少,车船直接转运量仅占年吞吐量10～20％。因此在港口建设中,平面布置、装卸工艺、码头结构型式都应考虑港口的通用性。
The characteristics of the construction of the middle and lower reaches of the Yangtze River except for the large water level difference (8-15 meters) and the deep buried layer are deep buried. In respect of waterway, the port is mainly responsible for the exchange of domestic urban and rural materials. In general ports, the ships have different types and cargo types , Less bulk cargo, the direct transport volume of vehicles and vessels only accounted for 10 to 20% of the annual throughput. Therefore, in the port construction, layout, loading and unloading technology, terminal structure type should consider the port’s versatility.
