摘　　要：结合京唐港区盐驳泊位的浚深改造工程,针对原结构断面的复核、提出了全遮帘桩设计方案和两种相应的计算方法;为进一步提高断面承载能力对全遮帘桩前加短桩方案也进行了计算分析,对为保证两套板桩系统协同工作而在两道新锚碇墙之间挤密砂桩的设置等问题做了较详细的论述。文中就两套独立板桩系统对设计提出的一些新的问题提出了见解,本工程的做法对于老板桩码头的浚深改造具有较为普遍的意义。In conjunction with the reconstruction works to dredge deeper in front of the salt berth in Jingtang Port and in view of the verification of the original structural cross--section and the proposal of a whole covered sheet pile structure,two corresponding computational methods are proposed and a scheme of fixing short piles in front of the whole covered sheet piles is also calculated and analyzed to further improve the sectional bearing capacity. In the meantime ,issues like sand compaction piles installed between the two new anchorage walls to ensure the coordinated working of the two types of sheet piling systems are also expounded in detail. Views are raised for the issues in the designs for the two independent sheet piling systems. The method used on this project is of general significance for the deep--dredging and reconstruction of old sheet pile wharfs.
