摘　　要：不同的墩塔梁固结形式对矮塔斜拉桥的自振特性有不同的影响。本文通过对北京至上海新建高速铁路工程天津枢纽津沪联络线特大桥进行有限元分析,得出该矮塔斜拉桥的自振特性,同时给出三种对比模型的自振特性,并将这几种模型进行对比分析,得出一些有参考意义的结论。The different pier-tower-girder consolidated forms have different effects on the self-vibration characteristics of partial cable-stayed bridge.The self-vibration characteristics of the Beijing-Shanghai traverse grand bridge in tianjin hub of Beijing-Shanghai high-speed railway engineering are analyzed by the method of finite element in this paper,meanwhile the conclusions are contrasted with conclusions of other three modes.These conclusions have certain reference significances to the similar projects.
