| 高桩码头横向排架内力通常简化为平面结构进行计算，但码头端部的排架作为艏艉缆绳的受力排架或受制于相邻结构的影响，其桩基布置往往不同于其他排架，平面计算并不能准确反映端部排架的受力和变形。结合鱼山出灰码头桩基布置设计实例，采用平面计算法和空间计算法对水平荷载作用下码头结构分段端部排架不同桩基布置方案进行对比分析，得出不同计算方法及不同桩基布置下各排架桩基内力和变形计算结果的差异。结果表明，对于对称性水平荷载，平面计算的桩基轴力结果与码头结构分段端部自由的端部排架桩基轴力结果基本相当；对于非对称性水平荷载，平面计算的桩基轴力结果普遍大于空间计算的结果；端部排架布置双排桩加强后，码头结构的位移会有一定程度减小。 |

| The internal force of piled wharf transverse bent is usually simplified as a plane structure to calculate，but the end bent of the wharf as the stressed bent of the bow and stern cables，is affected by the adjacent structures. The pile foundation layout of end bent is different from other bents，and the simplified plane calculation cannot accurately reflect the force and deformation of the end bent. Based on the example of pile foundation layout design of Yushan ash loading wharf，we use the plane calculation method and space calculation method to compare and analyze different pile foundation layout schemes of the end bent of wharf structure under horizontal load，and obtain the differences of calculation results of internal force and deformation of each pile foundation under different calculation methods and pile foundation layout schemes. The results show that for the symmetric horizontal load，the axial force of pile foundation calculated by the plane calculation method is equivalent to that of pile foundation of end bent with the free end of wharf structure. For the asymmetric horizontal load，the axial force of pile foundation calculated by the plane calculation method is generally larger than that calculated by the space calculation method. The displacement of the wharf structure is reduced to a certain extent after the end bent is strengthened with double row piles. |
