摘　　要：全简支梁结构具有快速装配的优点,但由于对其水平力传递性能研究不足,在装配式高桩码头中应用较少。通过有限元模型计算对比,分析了全简支梁结构受水平集中力情况下码头结构的位移分布规律。结果表明:全简支梁体系对码头结构水平力传递性能削弱的影响较小,在面层连续的情况下能有效传递水平力,是可行的装配式技术方案。采用全简支梁体系的高桩码头结构宜在《码头结构设计规范》规定的基础上,将水平力分配系数及计算位移值适当提高。The simply supported beam structure has the advantage of rapid assembly,but it is seldom used in prefabricated high-piled wharf due to the lack of research on its horizontal force transmission performance.This paper analyzes the displacement distribution law of wharf structure subjected to horizontal concentrated force through the comparison of finite element model calculation.The results show that the full simply supported beam system has little effect on the weakening of horizontal force transfer performance of wharf structure,and can effectively transfer horizontal force under the condition of continuous surface layer,which is a feasible prefabricated technical scheme.For the piled wharf structure with full simply supported beam system,the horizontal force distribution coefficient should be appropriately increased on the basis of standard regulations in Design Code for Wharf Structure.
