老码头升级改造中窄长高桩结构设计优化

越来越多的老码头使用年限到期或者因为业务发展,需要升级改造,而可用于升级的空间却有限,因此对于限定空间的老码头结构改造,研究窄长码头的结构形式是有必要的。基于实例,分析地质变化以及原设计方案的局限性,结合试打桩情况,将原设计高桩梁板方案调整优化为高桩墩台方案。理论计算和施工结果均表明,该设计优化可以适应窄长结构段的复杂地质,对于类似的改造工程具有借鉴意义。

Design optimization of narrow and long pile structure in upgrading and renovation engineering of old wharf

Nowadays,more and more old wharf need to be deepening and strengthening to meet the requirement of large ship displacement due to their service life or business development,but the space for updating is limited.Therefore,it is necessary to study the structural type of narrow and long wharf with limited space.This paper analyzed the geological change and the limitation of the original design scheme in one project,combining with the trial pile,and adjusted the design from elevated pile and beam-slab structure into pier platform structure.Theoretical calculation and construction results show that this design optimization can adapt to the complex geology of narrow and long structure,and it has reference significance for similar reconstruction projects.
