新型重力式箱肋结构设计

依托汉班托塔港二期项目的干地施工条件,提出一种新型的箱肋式结构。针对结构各组件功能、计算模式、受力特性及计算结果进行研究。采用ANSYS软件计算得出各构件内力,并就此结构内力特性与常规沉箱结构的差异进行分析。结果表明:新型箱肋式结构既有沉箱结构整体性好的优点,又有扶壁结构低成本优势,同时后续施工速度更快。

Design of a new gravity type box-buttress caisson structure

Based on the dry construction condition of the Hambantota Port Development Project Phase II,we propose a new type of buttress caisson,and study the function,calculation mode,mechanical characteristics and calculation results of each component of the structure.Adopting software ANSYS,we obtain the internal forces of members through calculation and analyze the characteristics between the buttress caisson and the conventional caisson.The results show that the new type buttress caisson not only has the advantages of good integrity of the caisson structure,but also is of low cost.Besides,the subsequent construction speed is faster.
