| 摘 要： | 基于位移协调、力的平衡和能量守恒原理,通过在水平桩NL法计算中引入桩侧土抗力群桩折减系数,采用Lagrange插值多项式拟合护舷厂家的反力、吸能与变形的关系曲线,对柔性靠船桩簇中钢桩和护舷间水平力、能量分配进行计算分析;并将之应用在某码头的靠船桩簇设计中,取得了良好的成效。

| Abstract: | Based on the principle of displacement compatibility,force balance and energy conservation,considering the discount coefficient of the lateral soil resistance on piles in the NL method,and fitting curves between the deformation and stress of the rubber fender,we analyze the energy allocation of steel-pile cluster and rubber fender.The result was applied to the design of the clustered fender piles in the jetty project of Moulmein and achieved a good effect. |
