摘要
综述悬索桥在国内外的发展现状与前景 ,指出对锚碇系统进行详细研究的必要性 .在详细介绍锚碇系统传力过程的基础上 ,分别从锚碇系统的稳定性、变位、强度与温度应力、施工力学、优化等几个方面阐述锚碇系统力学分析的现状 ,讨论现有分析方法的缺点 .文末针对基础失稳的力学机制、长期变位中的蠕变特性、考虑结构与基础相应作用及场耦合的三维有限元模型、施工力学模型、参数确定。
In this paper,the present situation and future development of suspension bridges are described.The necessity of detailed research of anchorage is pointed out.On the basis of dicussion on the mechanical process of anchorage,the present situation of mechanical analysis of stability,deformation,strength and temperature stress,construction mechanics,and optimization of the anchorage is analysed,and the drawback of present methods is discussed.Finally,a series of problem existing in the study of the mechanism of instability,creep in long term deformation,the finite element model taking account of the impact of structure and foundation and coupling of various spaces,construction mechanics model,the determination of coefficients,and feed back design are identified.
