摘　　要：将疲劳力学理论引入靠船墩结构分析,探讨靠船墩的疲劳破坏问题,并进行疲劳可靠度研究.提出了靠船墩疲劳可靠度计算方法,据此可进行靠船墩的疲劳寿命预报,直接指导工程优化设计和施工,分析桩空间布置对结构受力状况和疲劳强度的影响,增大结构的刚度,从而达到经济、安全的目的.In accordance with an analysis of pier structures by the theory of fatigue mechanics, the fatigue failure of pier structures is discussed, and a method is proposed for calculation of the reliability of fatigue of pier structures. The method also provides a basis for prediction of the fatigue life of pier structures, direct guidance to the optimal design and construction of engineering projects, and analysis of the influences of the spatial arrangement of piles on the stress and fatigue strength of structures, so as to intensify the stiffness of structures and ensure less cost and high safety.
