高桩码头结构新型加固改造方案设计

为提升码头靠泊能力，对某集装箱码头进行加固改造设计。针对其前、后平台横梁位于同一轴线上的特点，提 出采用铰接传力杆连接前、后平台的新型改造方案。并采用Easydoing和Robot等计算软件，对码头改造前后进行内力分析 和传力杆计算。分析结果及传力杆现场实测结果表明，新型改造方案能改善码头结构受力情况，满足其超设计船型的靠泊要 求，并且连接前、后平台方案施工方便，工期短，对正常生产影响小，造价低，为码头加固改造设计提供了一种新的思路。

New design scheme of reinforcement and reconstruction for pile-supported wharf

In order to improve the berthing capacity, we carry out the reinforcement and reconstruction design to a container terminal. Considering that the beams on both the front and the back of the pier lies on one axis, we propose a new solution in which the front and the back of the pier are hinged by the dowel bar. Software Easydoing, Robot, etc. are used for the internal force analysis of the pier structure before and after the reconstruction.It is concluded from the analysis and the results of the dowel-bar test site that the new solution of reinforcement and reconstruction can surely improve the stress distribution of the pier structure. The reinforced and reconstructed pile-supported pier can meet the berthing requirement for all vessel types. In addition, the front and the back of the pier being hinged together have the advantages as more construction convenience, shorter construction period, less effect on routine operation and lower cost. The solution proposed also provides a new thought for the design of the reinforcement and reconstruction.
