摘　　要：本文运用Autodesk Robot Structural Analysis Professional软件对水平集中力在四跨高桩框架码头的分配系数进行研究。着重分析了不同作用排架、不同作用高程和不同排架间距对水平集中力分配系数影响的变化规律。结果表明:由于高桩框架码头结构整体受力性能更好以及水平集中力作用点高程变化大等特点,四跨高桩框架码头中水平集中力分配系数不能单纯按照《码头结构设计规范(JTS 167-2018)》附录F中的规律进行推算选取。本文研究结论对规范做了一定适应性验证,为高桩框架码头平面排架计算水平集中力分配系数选取提供了合理化建议,可供类似工程参考和借鉴。The distribution coefficient of horizontal force acting on four-bent piled frame berth is studied by using Autodesk Robot Structural Analysis Professional, especially the change rules for the impact of different bents,elevations and bent spacing on horizontal force distribution coefficient. The results show that the piled frame berth structure is of better overall bearing performance and there is great change in the elevation of the point which the horizontal force acts on. Thus the distribution coefficient of horizontal force acting on four-bent piled frame berth cannot be calculated and selected according to Appendix-F specified in Code for Design of Berth Structure(JTS 167-2018). The above research results are used to verify the applicability of the Code to a certain extent. In addition, some suggestions are put forward for the selection of horizontal force distribution coefficient in the calculation of plane bents of piled frame berth, which will serve as a reference for similar projects.
