三峡库区变动回水区港口码头合理型式分析

Analysis for the reasonable dock and port form in fluctuating backwater area of the Three Gorges Reservoir

三峡水库蓄水后,对三峡库区合理港口码头结构型式进行分析,并针对三峡库区变动回水区特殊的地形、地质和水文条件,提出大桩径大跨度架空直立式新型码头结构型式,对以后类似于长历时大水深和大变幅水位问题造成的库区复杂水文和地质等环境条件码头的建设都具有指导意义。

After the operating of water storage of Three Gorges Reservoir, the dock and port forms around the area had been analyzed, and according to the special terrain, geology and hydrology in the changing backwater area, a big pile diameter vertical large-span overhead structure is put forward, which has guiding significance for the similar long after the last major water depth and water level variation in the reservoir area caused by the complexity of the issue of hydrological and geological conditions.
