斯里兰卡汉班托塔港二期码头结构优化

摘要

结合斯里兰卡汉班托塔港口二期工程干地施工的条件，在一期码头常规沉箱的基础上提出了多种结构优化形式，对优化思路进行分析对比，最终采用新型箱肋式重力码头结构，体现了沉箱结构整体性好的特点，充分利用扶壁结构的受力特点，解决扶壁结构应用于大型码头结构时受力较大的问题。%Combined with the dry construction condition of Hambantota Port development project phase II in Sri Lanka, based on the regular caisson for Hambantota Port development project phase I, we put forward multiple optimized structure types. Through the comparative analysis of them, we finally adopted the new type buttress caisson gravity wharf structure, which re-flects that the caisson has good structural integrity, making full use of the loading features of buttress, and solving the problems for the buttress applying on large wharf.
