摘　　要：以湖南某码头改造项目为例,介绍了高水位差柔性防撞桩簇的设计分析要点。基于NL计算方法,推求高水位差防撞桩簇的弹性系数变化规律,通过各桩作用点位移相协调和力的平衡来对桩簇水平力、能量分配进行分析;并计算了桩簇内力和变位,对防撞桩簇的设计进行验证。结果表明:高水位差防撞桩簇应分区段选用不同型号的护舷,以发挥护舷吸能的优势。Taking a wharf reconstruction project in Hunan province for example, we introduce key design points of the flexible breasting clustered piles with large fluctuation. Based on the NL method, we get the variation law of the pile＇s elastic factor, and analyze the horizontal force and energy distribution between piles and fender by considering the displacement compatibility and static balance. We also calculate the stress and deformation of the pile cluster, and verify the design of fender piles cluster. The results show that we should choose the fitted fender in different sections of the flexible anti-collision pile cluster, which gives play to energy- absorbing advantages of the fender.
