摘　　要：高桩结构形式在海港工程中应用广泛,结构设计需要考虑复杂的荷载和繁多的工况组合,进行全工况包络计算往往需要付出巨大的代价,如果受计算时间、计算条件的限制进行简化,则会错过最危险工况或降低计算精度。鉴于此,提出了自动化全工况包络优化设计方法,并结合SQLite与Python开发了相应的自动化管理与计算平台。该方法基于通用计算程序对独立荷载的计算结果,首先对广义均载、广义流机荷载的分布多态性进行预处理,降低计算复杂度,再通过n维空间的笛卡尔积和矩阵运算分别计算全工况组合列表和离散位置的荷载作用效应,最后输出全工况包络图。该设计方法能够大幅提高计算效率,为高桩结构构件的高效化、精细化设计奠定了技术基础。The open-type wharf is widely used in port engineering. Due to the complexity of load combinations, calculation that covers full load combinations usually costs a lot of time. When simplification is applied, accuracy will be sacrificed or most dangerous load combination may be missed. An automatic calculation method is put forward and corresponding data management platform is built on SQLite and Python. Load effect is calculated on single effect by Staad.First of all, the distribution polymorphism of generalized uniform and generalized mobile loads is dealt with, then the load effect of discrete position of all members is computed.Envelope diagram is the final output of this method.The method greatly reduces computational complexity and highly increases efficiency. The achievement of this article makes refined and accurate design possible.
