摘　　要：以在建的重庆市两江新区果园枢纽港二期工程为例,采用有限元法对内河大水位差架空直立式框架码头单排架结构进行了受力分析。探讨了不同荷载组合下的最不利受力构件。按照恒载参与每种作用效应组合,活载按结构实际可能出现的受力情况进行组合分析的思路,对结构自重、面板自重、堆货荷载、岸吊荷载和船舶撞击力等荷载进行组合,共设计了32种荷载组合。采用有限元法计算分析每种组合下的排架结构各构件的内力,在32种荷载组合结果中搜索各构件的最大(小)内力值,从而确定在32种荷载组合下的最不利受力构件,并得到了控制结构构件内力的21种最不利荷载组合。Take the under construction of Guoyuan hub port phase Ⅱ project , which is in Liangjiang new dis-trict of Chongqing as an example, finite element method is used for stress analysis of single bent structure of inland river wharf , and discusses the most unfavorable stress components of the bent structure in different load combina-tion. Load combination of Guoyuan hub port phase II project is conducted though the way of dead load participate in each kind of effect combination and live load portfolio analysis according to the actual stress situation that may oc- cur. Dead load, weight of panel, pile of cargo loading, shore crane load and ship impact force are combined, and 32 kinds of loading combination were designed. Using finite element method calculation the force of component of the bent structure under each loading combination, Search the maximum （small） internal force of every component in 32 kinds of loading combination, and determine the most unfavorable component in 32 kinds of loading combina-tion. And get 21 kinds of the most unfavorable load combination, which control of structures internal force.
