新型整体卸荷式板桩码头设计

Design of New Type Monolithic Unloading Sheet Pile Wharf

本文提出了一种在国内尚未广泛采用的以管式钢板桩作为前墙的整体卸荷式板桩码头的结构型式,并较详细地说明了设计方法。这种结构型式适用于万吨级以上大型码头,不仅施工进度快,而且避免了水下施工这种艰苦困难的工序,比同条件下的重力式码头可以节省造价20%以上,代表了大型码头结构更新换代的发展方向。

This paper presents a structural type of integral unloading sheet pile wharf with tubular steel sheet pile as front wall, which has not been widely used in China, and the design method is explained in detail. This type of structure is suitable for largescale wharves above 10,000 tons, not only the construction progress is fast, but also the difficult working procedure of underwater construction is avoided. Compared with the gravity type wharf under the same conditions, the cost can be saved by more than 20%. It represents the development direction of the upgrading of large-scale wharf structure.
