摘　　要：波浪条件是游艇码头浮桥结构设计的控制性因素。针对拉簧锚碇式混凝土浮桥结构在波浪作用下运动和受力情况复杂的问题,依托实际工程,归纳游艇码头浮箱和锚碇结构选型的一般思路和原则,找出拉簧锚碇式混凝土浮桥的适用情况和结构设计要点,并通过有限元分析拉簧锚碇式混凝土浮桥在波浪作用下的运动响应及结构应力特点。结果表明,波浪超过0.5 m时,宜采用三维有限元数值分析手段重点分析浮桥结构的波浪响应特性,并在浮桥平面设计和结构详细设计时充分考虑。Wave is the controlling factor in the structural design of a pontoon for a yacht wharf.Given the complex motion and stress conditions of a spring anchorage concrete pontoon in waves,we focus on an actual project to summarize the general ideas and principles of selecting buoyancy tanks and anchorage structures for the yacht wharf.Then,we investigate the application conditions of the spring anchorage concrete pontoon and the main points in the structural design of such a concrete pontoon and use the finite-element method to analyze the motion response and structural stress characteristics of the concrete pontoon in waves.The results show that three-dimensional finite-element numerical analysis can be performed to analyze the wave response characteristics of such pontoons when the wave height exceeds 0.5 m and that this issue should be given due consideration in the general layout and detailed structural design of this type of pontoons.
