根据荷载组合原则，在以往研究成果的基础上经改进得到了一种可用于寻求任意排架数量的内河架空直立式码头三维空间结构各构件的最不利荷载工况组合算法。该算法是基于码头三维模型分别在不同荷载工况作用下各构件的内力结果，通过MATLAB编程来实现对该结果的线性叠加计算，从而找到各构件的最不利荷载工况组合情况。该算法有效克服了在以往二维平面模型计算中对门机及堆货荷载工况数量的局限性，使得最终计算结果更趋于真实。并以重庆港果园码头二期工程项目中五排架模型为例，运用该算法将结构原本可能出现的158738112种荷载工况组合简化到了最不利的14种情况，极大减少了设计计算过程中的工作量，可为内河大水位差架空直立式码头结构的设计与研究提供一定的技术支撑。

According to the principle of load combination,this paper deduce a algorithm for each component’s worst load case combinations in 3D structure of vertical-faced wharfs in inland rivers for any number of bent on the basis of previous research results. This algorithm is on the basis of each component’s internal force results in 3D structure wharfs respectively under the different load conditions. The way of MATLAB programming realize the linear superposition of the calculated results, so each component’s worst load case combinations can be found. The algorithm effectively overcomes the Limitations of the number of portal crane and cargo load cases in 2D models formerly, making the final calculated results tend to be more accurate. And taking Chongqing Guoyuan Wharf second project in five frame model as an example. Eventually 158 738 112 kinds of effects of load case combinations which might appear respectively are simplified to 15 kinds by this algorithm. This algorithm greatly re-duces the calculation workload of design and provides certain technical support for design and research to the inland vertical-faced wharf of great water level difference structures.
