摘　　要：为保证港口安全,适应沿海港口吞吐量增长和到港船舶大型化发展,对已建高桩码头进行升级加固改造成为必然趋势。作为一种新型方案,传力杆技术已在部分高桩码头升级改造中得到应用。结合相应工程实例,对传力杆加固高桩码头升级改造技术特点、设计计算方法及相应的施工工艺进行系统阐述,并采用专业软件进行码头整体建模,对传力杆加固高桩码头效果进行了验证,结果表明横梁和桩基内力都有一定程度的改善。In order to ensure the safety of the port and adapt to the growth of the coastal port throughput as well as large-scale development of the ship, the upgrading and strengthening of the high piled wharf has become an inevitable trend. As a kind of new scheme, the dowel bar technology has been applied to upgrading and reconstruction for high-piled wharf. Combining with engineering examples, the dowel bar of upgrading technical features for high-piled wharf reinforcement, design calculation method and the corresponding construction technology is described; using professional software for the wharf modeling, the dowel bar reinforcement effect of high pile wharf is verified.The results show that the beams and internal force of pile have a certain degree of improvement.
