撞击力下柔性靠船桩高桩码头横向变形分析

Study on lateral deformation of flexible berthing pile of high piled wharf under ship impact load

柔性靠船桩高桩码头是由靠船桩、护舷和桩台组成的一个结构系统。针对柔性靠船桩高桩码头桩台承受撞击力的情况,通过分析桩、护舷及桩台的受力及变形,利用桩顶处力的平衡条件和位移协调条件进行数学公式推演,导出了该系统横向变形的计算表达式,给出了表达式中相关系数的计算方法,并阐述了该表达式的迭代解法步骤。研究成果可为相关结构的设计及规范修订提供参考。

Flexible berthing pile of high piled wharf is a structural system composed of flexible berthing pile, rubber fender and pile platform. Aiming at the condition of the platform sustained the impact load, the lateral deformations of the pile, rubber fender and the pile platform were studied. The mathematical formulas were put forward on the basis of the horizontal force balancing condition and displacement coordination at the top of pile. The method to evaluate the correlation coefficients of the formulas was suggested, and the solving process of iterative method was described. The result can offer a reference for structure design and standard revision.
