洋山深水港区二期工程简介及与一期工程之异同

上海国际航运中心二期工程是在总结一期工程设计施工经验的基础上,依据二期工程所处小洋山本岛前沿陆域纵深相对较小,港区陆域欠规正,成陆地基有山体基岩和深层淤泥等复杂条件,遵照“归顺水流,减少淤积,安全靠泊”的原则及与一期工程可合并经营、统一管理,也可分开管理、独立经营的原则进行港区布置。实现了同一期码头前沿一致的-16m水深,加长了泊位长度,优化了设备选型,提高了泊位通过能力。同一期工程比较,用每个泊位相对较低的投入取得了更高的吞吐能力与经济效益。

Introduction to Phase Ⅱ of Yangshan Deep Water Port Project and Comparison with Phase Ⅰ

On the basis of a summing-up of the experience in design and construction of the works for Phase I of the Yangshan Deep Water Port Project and in view of the fact that the land area of the shore front of Xiaoyangshan, where the works for the second phase of the Yangshan Deep Water Port Project are located, is relatively small, the land area of the port is not clear and neat, and the land area is founded on bedrocks and deep-laid silt, the layout of the port has been worked out on the principle of regulation of the water flow, reduction of siltation and safe berthing of ships as well as on the principle that, upon completion, Phase II of the Project can not only be operated and managed together with Phase I of the Project but can also be operated and managed independently. As a result, the water depth in front of the berths of Phase II of the port is made to -16.0 m which is the same as that of Phase I of the port, the length of the berths is increased and the types of the equipment are also optimized, thus increasing the throughput.capacity of the berths. Compared with the berths at Phase I of the port, each berth at Phase II of the port produces higher throughput capacity and higher economic benefit with a relatively low investment.
