Research on Port Construction Technique after Water Storage of the Three Gorges Project

With the Three Gorges reservoir built up, the water level rises sharply and the low construction water level in dry season does not exist. The relatively low water level is in draw-off period and building port faces long time of deep water level and precipitous fluctuation of water level in flood period. There are huge quantities under water. The construction period of low water level is short and the height of water level is up to 30 meters. Port construction is more difficult and complex at the Three Gorge reservoir region. This paper aims at these situations and puts forward the port constructing technique in deep water areas. It will provide guidance and reference in wharf construction.
