摘　　要：基于单位力法,计算得到内河架空直立式码头三维结构模型在多种工况条件下各主要受力构件的内力结果,并经MATLAB编程进行组合、搜索,最终将内河架空直立式码头三维模型中原本可能出现的90 177 536种主要作用效应组合简化到14种,大大减少了计算工作量,研究成果可为内河架空直立式码头的结构计算与分析提供参考。Based on the unit force method, this paper gets the internal force results of each main force support component of one inland vertical-faced wharf under calculating the action of a variety of conditions of the wharf＇s three dimensional structure model, and by the combination and searching for the force results through MATLAB program, eventually 90 177 536 kinds of main effect combinations may appeared in 3D structure of vertical-faced wharfs in inland rivers are simplified to 14 kinds. This method and thinking greatly reduces the calculation workload. It can be applied for structure＇s calculating and analyzing in vertical-faced wharfs in inland rivers.
