根据我国三十余年的筑港经验,在长江沿岸筑港与沿海、河口相比,有如下特点: 1.港口能否正常运营与河势稳定程度休戚相关; 2.码头岸坡稳定问题与河道的演变历史有密切关系; 3.除河口外,江水位变化幅度很大; 4.沿岸的土质变化大,地质结构复杂。 如果对上述特点认识不足或措施不力, According to more than thirty years of experience in building a port in our country, there are the following characteristics compared with the estuaries built on the coast of the Yangtze River: 1. Whether the port can operate normally and the stability of the river regime are interrelated; 2. The stability of the quayside The history of the evolution of the river course is closely related; 3. In addition to the estuary, the river water level changes greatly; 4. Coastal soil changes, geological structure is complex. If you do not have enough understanding of the above characteristics or measures,
